11.2 Overview
Port A is a general purpose 8 bit wide digital input port, with interrupt capability. Figure 11-1 shows its structure.
© Semtech 2005
Input port, 8 bits wide
Each bit can be set individually for debounced or direct input
Each bit can be set individually for pull-up or not
Each bit is an interrupt request source on the rising or falling edge
A system reset can be generated on an input pattern
PA[0] and PA[1] can generate two events for the CPU, individually maskable
PA[0] to PA[3] can be used as clock inputs for the counters/timers/PWM (product dependent)
PA[0] can be used to enable the RC oscillator
