BOARD LAYOUT
POWER SUPPLY CIRCUIT
MSP430-H2274 power supply depends on the state of jumpers P_IN and P_OUT.
VCC_IN goes on JTAG connector pin 2 and VCC_OUT goes on JTAG connector pin
4.
RESET CIRCUIT
MSP430-H2274 reset circuit includes pin 11of JTAG connector, pin 7 of Extension
connector - CON1, MSP430F2274 pin 7.
CLOCK CIRCUIT
Quartz crystal 32768MHz is connected to MSP430F2274 pin 5 (XOUT/P2.7) and
pin 6 (XIN/P2.6).
JUMPER DESCRIPTION
Power In jumper:
P_IN jumper connects power supply from JTAG connector to Header
board. When this jumper cap is placed you can program the microcontroller even
without any other external supply. Note that if the Header board is placed in target
circuit, you have to ensure that your circuit doesn't draw more than few
milliampers current or the power supply may decrease due to the JTAG port
current limitations. P_IN is useful and must be used mostly to program your
header board when it's not put on your target circuit socket.
Power Out jumper:
P_OUT jumper connects power from Header board to JTAG connector.
When this jumper cap is placed, the power supply of JTAG connector will follow
the power supply of Header board. This is useful when your Header board (target
circuit) works at lower than +3,3V power supply.
Note:
P_IN and P_OUT jumper caps should not be placed at the same time.
