Power Supply of Memory Card can be selected by Jumper
J26(SD/VDD); so we can select to use Power Supply either from +VDD of Board or from the control of signal Pin MCIPWR. Normally, we set Jumper
J26(SD/VDD) on SD side to use Power Supply of Memory
Card from the control of MCIPWR. All circuits to connect with Memory Card uses signal pins from MCU as follows;
• MCIDAT0 uses P0.22.
• MCIDAT1 uses P2.11.
• MCIDAT2 uses P2.12.
• MCIDAT3 uses P2.13.
• MCICMD uses P0.20.
• MCICLK uses P0.19.
• MCIPWR uses P0.21.
•

•
UART-0 uses signal pin from P0.2(TXD0) and
P0.3(RXD0).
•
UART-2 uses signal pin from P0.10(TXD2) and
P0.11 (RXD2).
Because Hardware UART of LPC2368 can configure many points of signal Pin to connect; for example,
UART-2 can use signal Pin P0[10] and P0[11] or signal
Pin P2[8] and P2[9]. Board CP-JR ARM7 LPC2368 selects signal Pin P0[10] and P0[11] to be the connecting point with UART-2; so, we must set command to use signal Pin correctly. Be careful if we use UART because the Default value of UART-2 is disabled, so we must enable operation of UART-2 Circuit before command to Initial values for UART, otherwise we can not command UART. The example Code to configure initial values for UART is shown below.
// Config UART-0 Connect to P0[2]:P0[3]
PINSEL0 &= 0xFFFFFF0F; // Reset P0.2,P0.3 Pin Config
PINSEL0 |= 0x00000010;
PINSEL0 |= 0x00000040;
// Select P0.2 = TxD(UART-0)
// Select P0.3 = RxD(UART-0)
// Config UART-2 Connect to P0[10]:P0[11]
PINSEL0 &= 0xFF0FFFFF;
PINSEL0 |= 0x00100000;
PINSEL0 |= 0x00400000;
// Reset P0.10,P0.11 Pin Config
// Select P0.10 = TxD(UART-2)
// Select P0.11 = RxD(UART-2)
// UART2 Power-ON PCONP |= 0x01000000;

Application of RS422/485
For RS422/485 Communication Circuit of Board CP-
JR ARM7 LPC2368 uses UART-3 and then use signal Pin
P0[0] and P0[1] to be the connecting point. We can use this circuit to configure operation of Line
Driver Circuit to be either RS422 (Full Duplex) or
RS485 (Half-Duplex).
If it is RS422, it can transmit and receive data simultaneously as bidirectional as
RS232 but this function is longer distance. On the other hand, if it is RS485, we can configure its format of communication to be either Half-Duplex or
Full Duplex; in this case, if it is RS485 (Full-
Duplex), it is similar to RS422 but we must control
ON/OFF circuit of the transmitter; on the other hand, if it is RS485 (Half-Duplex), it will alternate function between receiver and transmitter by using signal P1[19] to be Output Port function for setting the direction of data.
If status of P1[19] is Logic
“1”, it configures the direction of data to be transmitter but if status of P1[19] is Logic “0”, it configures the direction of data to be receiver. The
IC Line Driver of circuit can select either No.75176 or MAX3088; if using 75176, the maximum point that can be connected signal of RS485 as Multi-Drop type is 32 points; but if using MAX3088, the maximum point that can be connected as Multi-Drop type is 256 points. The connector of RS422/485 is CPA-6 Connector that has arranged as shown below.

IC Line Driver as same as RS422; but in this case, we must set Jumper J19 and J20 to be RS485 (Full Duplex) as follows; set Jumper J19 (FULL/HALF) on FULL side and then set Jumper J20 (422/485) on 485 side. The

operation is similar to RS422 because it can simultaneously transmit and receive data as bidirectional type like RS422 but it can be connected as Multi-Drop type. The circuit can receive data all the time through IC Line Driver of U6 and IC Line
Driver U7 will transmit data.
In this case, it can control ON/OFF operation of transmitting data by signal from P1[19]; if status of P1[19] is Logic “1”, it enables operation of transmitting data but if status of P1[19] is Logic “0”, it disables operation of transmitting data. When the operation of transmitting data is disabled, its status is similar to removing cable of the transmitter from circuit, so signal on the transmitter does not crash data of other devices. We must write program to control all devices to transmit only one data into a line once.
If using RS485 (Half-Duplex), we must install only one IC Line Driver at position U7; in this case, we must set Jumper J19 and J20 to be RS485 (Half
Duplex) as follows; set Jumper J19 (FULL/HALF) on
HALF side and then set Jumper J20 (422/485) on 485 side. Moreover, we must interface cable of CPA-6(J18)
Connector at the position TX(-) and TX(+); in this case, function of TX(-) is RS485(-) and function of
TX(+) is RS485(+). Direction and function of this signal RS485 depends on status Logic of P1[19] that is Pin Output Port and its function is Direction
Control.
The method to set Jumper of Fail-Save Resistor and Terminate Resistor is describes as follows; if
Board is generally installed in the beginning position and destination of these Jumper Cables, we must enable and then set Jumper(EN/DIS) of RZ, RL,
RH, TZ, TL and TH on EN side or always Enable. The
Fail-Safe Resistor (RL, RH, TL and TH) makes status
Logic in the signal cable is in the correct IDLE status while not receiving and transmitting any data.
For the Terminate Resistor (RZ and TZ) will compensate the resistance or Impedance that is occurred in the line if it is very long line.
Code for writing program to configure operation of UART-3 of RS422/485, we must use P0[0] and P0[1]

to be the connecting Pin and then use P1[19] to control the direction of receiving and transmitting data of RS485. Be careful, the Default value of the
UART-3 Circuit in LPC2368 is normally disabled; so, if we want to enable operation of this circuit, we must not forget to write command to enable operation of UART-3 before setting configurations into circuit.
The method to enable operation of UART-3 is to be controlled by Bit in Register PCONP as example below.
// Config UART-3(RS422/485) Connect to P0[0]:P0[1]
PINSEL0 &= 0xFFFFFFF0; // Reset P0.0,P0.1 Pin Config
PINSEL0 |= 0x00000002;
PINSEL0 |= 0x00000008;
PCONP |= 0x02000000;
// Select P0.0 = TxD(UART3)
// Select P0.1 = RxD(UART3)
// UART3 Power-ON
// Config P1.19 = Output Control Direction RS485
// P1.19 = "0" = Received RS485
// P1.19 = "1" = Transmit RS485
PINSEL3 &= 0xFFFF3FFF;
IODIR1 = 0x00080000;
IOCLR1 = 0x00080000;
// P1.19 = GPIO
// Pin Control Direction RS485 = Output
// Select Direction RS485 = Receive
// RS485 Direction = 0 (Receive)
// Select Direction RS485 = Transmit
IOSET1 = 0x00080000; // RS485 Direction = 1 (Transmit)
Port I/O Connectors of Board
For Port I/O Connector of CPU is arranged outwards, so it makes user be able to connect as desired; in this case, there are 6 sets as follows;
• 2 Sets of IDE 10 Pin Connector; each set has 8
Bit that is P2[0..7] and KEY4X4
(P0[4..7],P1[20..23]). Its signal arrangement is shown below.
