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.

13-1. 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> 1 2 3 4 Power supply POFF � L MPCA8 IRQ0 � L STOP � L RESET � L (System reset) Table 20 <Power ON> 1 2 Power supply POFF � H MPCA8 CPU CKDC9 RESET � H (System reset) CPU CKDC9
OK? Yes MRV reset
No OK? SRV reset Yes 10-key position input sequence MRV reset SRV reset No

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. Table 22 Built-in port P34 P35 P36 P37 Signal name DR0 DR1 DR2 DR3 Remarks Drawer 1 (optional drawer) Drawer 2 (optional drawer) Reserved Reserved
The table below shows the timing chart.

200ms MIN
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.
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.) 7 � 26
15. IR communication
Data is exchanged with the MPCA8 using the channel 1 (SCI1) of the serial communication interface of the CPU.
