Output
Output terminal of synchronous signal of 7.35kHz divided from quartz oscillation.
53
WRQ
Output
Output terminal to stand by output of subcode Q.
54
RWC
Input
Input terminal of read/write. Schmit input.
55
SQOUT
Output
Output terminal of subcode Q.
56
COIN
Input
Command input terminal from microcomputer.
57
/CQCK
Input
Clock input terminal to fetch command input, or pick up subcode from SQOUT. Schmit input.
58
/RES
Input
Reset input terminal of LC78622. When turning on power, set it at "L".
59*
TEST11 (NC)
Output
Output terminal for test. Used in the open state ("L" output as ordinary).
60*
16M (NC)
Output
Output terminal of 16.9344Hz.
61
4M
Output
Output terminal of 4.2336MHz.
62
TEST5
Input
Input terminal for test. Pull-down resistor is integrated. Surely connected to 0V.
63
/CS
Input
Chip selection input terminal. Pull-down resistor is integrated.
Connected to 0when not controlled.
Connected to 0when not controlled.
64
TEST1
Input
Input terminal for test. Pull-down resistor is integrated. Surely connected to 0V.
Pin No.
Note: The same potential must be supplied to the power terminals (VDD, VVDD, LVDD, RVDD, XVDD).
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
