Interrupts
5.2.3.3 Output Compare Interrupt
The output compare interrupt is generated by a 16-bit timer as described in
Chapter 8 Capture/Compare
Timer. The output compare interrupt flag is located in register TSR and its corresponding enable bit can
be found in register TCR. The I bit in the CCR must be clear for the output compare interrupt to be
enabled. The interrupt service routine address is specified by the contents of memory locations $1FF8
and $1FF9.
5.2.3.4 Timer Overflow Interrupt
The timer overflow interrupt is generated by the 16-bit timer as described in
Chapter 8 Capture/Compare
Timer. The timer overflow interrupt flag is located in register TSR and its corresponding enable bit can be
found in register TCR. The I bit in the CCR must be clear for the timer overflow interrupt to be enabled.
This internal interrupt will vector to the interrupt service routine located at the address specified by the
contents of memory locations $1FF8 and $1FF9.
