Section 11 Advanced Pulse Controller (APC)
11.3.2
Example of Setting Procedure for Advanced Pulse Controller Output Operation: Figure 11.3
shows an example of the setting procedure for advanced pulse controller output operation.
1. Set general registers GR2A and GR2B as output compare registers with the timer I/O control
2. Set the pulse rise point with GR2A and the pulse fall point with GR2B.
3. Select the timer counter 2 (TCNT2) counter clock with the timer prescale register (PSCR).
4. Enable the respective interrupts with the timer interrupt enable register (TIER).
5. Set the pins for 1 output and 0 output with POPCR.
6. Set the control register for the port to be used by the APC to the APC output pin function.
7. Set the STR bit to 1 in the timer start register (TSTR) to start timer counter 2 (TCNT2).
8. Each time a compare-match interrupt is generated, update the GR value and set the next pulse
9. Each time a compare-match interrupt is generated, update the POPCR value and set the next
