Input port for event counter

Event

Counter

Input

P3.1

P2.0 to P2.3 secondary functions :

These are level-triggered external interrupt input pins.

Select interrupt enable/disable for each bit with the

P2 interrupt enable register (P2IE).

If P2.0 to P2.3 pins are set to "H" level for a minimum

of 2 seconds, the device enters system reset mode.

P2.0, P2.1 secondary functions :

trigger input pins for capture circuit.

External

Interrupts

P3.0 secondary function :

This is an input pin for external interrupt. This pin can

receive an interrupt at a rising edge, a falling edge, or at

both rising and falling edges.
