13. Reset sequence
The reset sequence block diagram is shown below. Note that RESET
signal (system reset) and CKDCR signal (CKDC reset) are different
from each other.
Fig. 14
13-1. Power ON/OFF
The flow of signal processing at the time of the power supply turning
On/Off is as follows:

13-2. MRS, SRV reset
The UP-3300 does not have the mode switch. The procedure for
resetting MRS, SRV is different from that of conventional cash
registers.
in the UP-3300, MRS, SRV resetting is selected and executed by the
key which has bee depressed when the CKDC reset is released to
start the system.
(In the case of MRS, security is added by a key operation equivalent
to a pass word.)

14. Drawer
The UP-3300 can use up to 2 optional external drawers.
14-1. Drawer solenoid drive
P34
∼
P37 inside the CPU are allocated for the port output of the
drawer solenoid drive.

One port corresponds to one drawer. Theoretically, it is possible to
drive multiple drawers at the same time, but this processing must be
inhibited softwarewisely because of power supply capacity and driver
hardware factors. If a power failure is detected, the drawer solenoid
drive must be stopped as soon as possible.
*
The drawer solenoid drive time must controlled in the range of 40
ms to 50 ms by the timer.
14-2. 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.
15. IR communication
Data is exchanged with the MPCA8 using the channel 1 (SCI1) of the
serial communication interface of the CPU.
