4-4. Initilize IC (Reset circuit)
VDD: Voltage of memory protection battery
To Pin No.60 of CPU
When the voltage level at Pin No.60 of CPU is not stabilized, CPU does not work properly in rare case.
Therefore, this machine uses the initialize IC for stabilizing the voltage.
Even the voltage level of VDD (Pin No.2) is changed, Pin No.1 of initilize IC outputs stabilized 5 volts.
When the VDD voltage become less than 1.9 V, the initialize IC send a reset signal to CPU.
4-5. Power down detection circuit (PWD)
To Pin No.64 of CPU
When the VP voltage become less than 4.8 V, the pin No.1 of IC5 become “Low” level.
Then,the transistor Q44 become OFF.
When Q44 become OFF, the voltage lebel of pin No.64 of CPU changes to “High” level from “Low”. Then,
CPU knows power failure.
4-6. Address latch circuit
CPU uses 8 port (AD0 ~ AD7) for address bus and
data bus.
To select the address, CPU use the IC13.
CPU send the address to IC13, and send ASTB
signal at same time.
Then, IC13 store the address and output the
address immediately.
In this way, CPU select the address and data
signal.

TR5
Motor drive circuit
Normally, the transistor of motor drive circuit is followng condition.
TR1, TR2, TR5 : OFF
TR3, TR4 :
ON
MD (-) signal :
VP level
When the CPU want to rotate the motor, CPU change the MD signal to “High” from “Low”.
Then, TR1, TR2 and TR5 are become ON and MD (-) signal is become GND level,
and then motor is rotated.
Head drive circuit
When the CPU wants to print, CPU send “High” signal from HD.A ~ HD.H terminal.
This signal goes to printer unit, and then print.
RP: Reset pulse from printer
DP: Dot pulse from printer

4-9. VPP sensor circuit
Protection circuit
To prevent the circuit breakage, the protection circuit watches the voltage level of VCC, VDD and VPP.
When the each voltage level is more than following condition, this circuit cuts the voltage.
VCC,VDD:
In case these voltages are become over voltage, this circuit outputs “SCR”
signal(High signal) and burn out the fuse.
VPP:
In case the VPP voltage is more than 15 V or less than 13.9 V, the “VPP.S” level
is inverted and CPU cut the “VPP.ON” signal.
Detection voltage level (Unit: V)
VCC >= +6.5 V
VDD >= +6.5 V
+13.9 V =< VPP <=15.0 V
