Pin No. Signal I/O Description
25 P41 OUT Terminal not used.
26 P40 IN Connected to VC.
27 RESET IN
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied. Temporarily set "L"
level the moment power is applied, at this time the LSI is reset. Thereafter set at "H" level.
28-29 P71-P70 OUT Terminal not used.
30 XIN IN
Internal clock oscillation frequency input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with respect
to XIN terminal.
31 XOUT OUT
Internal clock oscillation frequency control output.
Output to control oscillation input of XOUT.
32 VSS IN
Power source voltage: -5.0V.
VC voltage of power source circuit input.
