/ P30-P33
I
I/O
/ OUT
Seament data sianals.
Refer to the touch control panel circuit for the relationship between signals and indicators.
Normally, one pulse is output in every synchronized signal period, and input to the anode of the fluorescen;t$,$sl;
PIN NO. / 5
1 SIGNAL ! ACL
I
I/O
1 IN
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is supplied.
Temporarily set to “L” level the moment power is supplied, at this time the LSI is reset.
Thereafter set at “H” level.
