13. RESET SEQUENCE
The reset sequence block diagram is shown below. Note that the
RESET signal (system reset) and CKDCR signal (CKDC reset) are
different from each other.
1) POWER ON/OFF
The flow of signal processing at the time of the power supply turning
On/Off is as follows:
Table 19<Power OFF>
Power supply MPCA9 CPU CKDC9

The table below shows the timing chart.
14. DRAWER
The UP-600 can use up to 2 optional external drawers.
1) DRAWER SOLENOID DRIVE
P34 ∼ P37 inside the CPU are allocated for the port output of the
drawer solenoid drive.
Built-in port Signal name Remarks
P34
DR0 Drawer 1 (optional drawer)
P35
DR1 Drawer 2 (optional drawer)
P36
DR2 Reserved
P37
DR3 Reserved
One port corresponds to one drawer. If a power failure is detected,
the drawer solenoid drive must be stopped as soon as possible.
The drawer solenoid drive time must be controlled in the range of
40 ms to 50 ms by the timer.
2) DRAWER OPEN/CLOSE SENSE
The drawer open/close sense signal is input into the built-in port of
the CPU. The sense signal of an optional drawer sensor is also wired
ORed before inputting.
• P33=1: Any of the drawers is open.
