Resets and Interrupts
13.3.2.9 KBD0–KBD7 Pins
A 0 on a keyboard interrupt pin latches an external interrupt request.
13.3.2.10 Analog-to-Digital Converter (ADC)
When the AIEN bit is set, the ADC module is capable of generating a CPU interrupt after each ADC
conversion. The COCO bit is not used as a conversion complete flag when interrupts are enabled.
13.3.2.11 Timebase Module (TBM)
The timebase module can interrupt the CPU on a regular basis with a rate defined by TBR2–TBR0. When
the timebase counter chain rolls over, the TBIF flag is set. If the TBIE bit is set, enabling the timebase
interrupt, the counter chain overflow will generate a CPU interrupt request.
Interrupts must be acknowledged by writing a 1 to the TACK bit.
13.3.3 Interrupt Status Registers
The flags in the interrupt status registers identify maskable interrupt sources.
interrupt sources and the interrupt status register flags that they set. The interrupt status registers can be
useful for debugging.
