To check the option I/F PWB from the solder side, connect the I/F
PWB to OPTCN2. To check from the parts side, connect to OPTCN3.
(Note) The option I/F PWB should be held horizontally so that no
excessive stress is applied to connecting section Ain Fig.
7-2.
[Procedure 2]
Fig. 7-3
Put a string between the pop up and the option PWB, as shown in

2-3. CKDC6 (HD404728A91FS)
1) General description
The CKDC6 is a 4-bit microcomputer developed for the ER-A460/
A470 and provides functions to control the real-time clock, keys, and
displays. The basic functions of the CKDC6 are shown below.
Keys: The CKDC6 is capable of controlling a maximum of 256
momentary keys. (Sharp 2-key rollover control)
Simultaneous scanning of key and switch
(When a key is scanned, the state of a mode and clerk
switch is also buffered. The host can scan the state of
switch together with the key entry data at the same time
the key is scanned.)
Switches: Mode switch with 14 positions maximum
8-bit clerk (cashier) switch
2-bit feed switch
1-bit receipt on/off switch
1-bit option switch
4-bit general-purpose switch (1-bit is used for keyboard
select)
Displays: 16-column dot display
12-column 7-segment display (column digit selectable)
All column blink controlled for the dot and 7-segment
display decimal point and indicators
Programmable patterns for 7-segment display:
Four patterns
Internal driver for 7-segment display
Buzzer: Single tone control
Clock: Year, month, day of month, day of week, hour, minute
Alarm: Hour, minute
Interrupt request (event control):
Detection of key input, switch position change, alarm
issue, and counter overflow
