(ADC10)
Up to 13 bidirectional input/output (I/O) lines and one input only:
Six shared with KBI
Six shared with ADC
Two shared with TIM
One input only shared with 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 or high/low level detect
Low-voltage inhibit (LVI) module features:
Software selectable trip point
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)
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
MC68HC08QY4, MC68HC08QY2, and MC68HC08QY1 are available in these packages:
16-pin small outline integrated circuit (SOIC) package
16-pin thin shrink small outline package (TSSOP)
