DESCRIPTION
Power supply input pins. Place the 0.1µF bypass capacitor between the VDD and VSS pin.
System reset pin. Schmitt trigger structure, low active, normal stay to “high”.
External oscillator input pin. RC mode input pin.
External oscillator output pin. In RC mode is P1.4 I/O.
Input / Interrupt (Schmitt trigger) / Wakeup function.
Bi-direction pins with sleep mode wakeup function.
Bi-direction pins.
Notice : The SN8P1602/3 do not have the pull-up resistor in the input port. The user must use the external pull-up
resistor.
