Figure 11.3 Example of Setting Procedure for Advanced Pulse Controller Output
Operation
Example of Advanced Pulse Controller Output Operation: Figure 11.4 shows an example of
advanced pulse controller output operation.
1. Set ATU registers GR2A and GR2B (to be used for output trigger generation) as output
compare registers. Set the rise point in GR2A and the fall point in GR2B, and enable the
respective compare-match interrupts.
2. Write H'0101 to POPCR.
3. Start ATU timer 2. When a GR2A compare-match occurs, 1 is output from the PULS0 pin.
When a GR2B compare-match occurs, 0 is output from the PULS0 pin.
