5 or 13 bidirectional input/output (I/O) lines and one input only:
– Six shared with keyboard interrupt function and ADC
– Two shared with timer channels
– One shared with external interrupt (IRQ)
– Eight extra I/O lines on 16-pin package only
– High current sink/source capability on all port pins
– Selectable pullups on all ports, selectable on an individual bit
– Three-state ability on all port pins
6-bit keyboard interrupt with wakeup feature (KBI)
Low-voltage inhibit (LVI) module features:
– Software selectable trip point in CONFIG register
System protection features:
– Computer operating properly (COP) watchdog
