General Description
• Enhanced serial communications interface (ESCI) module
• Serial peripheral interface (SPI) module
• 4-channel, 16-bit timer interface (TIM1) module
• 2-channel, 16-bit timer interface (TIM2) module
• 10-channel, 10-bit analog-to-digital converter (ADC) with internal bandgap reference channel
(ADC10)
• Up to 24 bidirectional input/output (I/O) lines and two input only:
– Six shared with keyboard interrupt function
– Ten shared with ADC
– Four shared with TIM1
– Two shared with TIM2
– Two shared with ESCI
– Four shared with SPI
– One input only shared with external interrupt (IRQ)
– High current sink/source capability on all port pins
– Selectable pullups on all ports, selectable on an individual bit basis
– Three-state ability on all port pins
• 6-bit keyboard interrupt with wakeup feature (KBI)
– Programmable for rising/falling edge or high/low level detection
• Low-voltage inhibit (LVI) module features:
– Software selectable trip point in CONFIG register
• System protection features:
– Computer operating properly (COP) watchdog
– Low-voltage detection with reset
– Illegal opcode detection with reset
– Illegal address detection with reset
• External asynchronous interrupt pin with internal pullup (IRQ) shared with general-purpose input
pin
• Master asynchronous reset pin with internal pullup (RST) shared with general-purpose input/output
(I/O) pin
• Memory mapped I/O registers
• Power saving stop and wait modes
