General Release Specification

Interrupts

4.11 Core Timer Interrupt

This timer can create two types of interrupts. A timer overflow interrupt

occurs whenever the 8-bit timer rolls over from $FF to $00 and the

enable bit TOFE is set. A real-time interrupt occurs whenever the

programmed time elapses and the enable bit RTIE is set. Either of

these interrupts vector to the same interrupt service routine, located at

the address specified by the contents of memory locations $1FF4 and

$1FF5.

4.12 Comparator 3 Interrupt

Comparator 3 can create an interrupt when its output (CMP3) gets set

and the enable bit CM3IE is set. The interrupt service routine is located

at the address specified by the contents of memory locations $1FFA and

$1FFB.
