12 X1 IN Connected to GND.
13 X2 OUT Terminal not used.
14 VSS IN Power source voltage: -5.0V.
VC voltage of power source circuit input.
15 OSC2 OUT Internal clock oscillation frequency control output.
Output to control oscillation input of OSC2.
16 OSC1 IN Internal clock oscillation frequency input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to OSC1 terminal.
17 TEST IN Connected to VC.
18 RES 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.
