Settings for Ordinary TPC Output (Figure 11.4):
1. Select GRA as the output compare register (output disable) with the timer I/O control register
2. Set the TPC output trigger cycle.
3. Select the counter clock with the TPSC2–TPSC0 bits in the timer control register (TCR).
4. Set the timer interrupt enable register (TIER) to enable IMIA interrupts. Transfers to NDR can
5. Set the initial output value in the I/O port data register to be used by the TPC.
6. Set the I/O port control register to be used by the TPC as the TP pin function (11).
7. Set to 1 the bit that performs TPC output to the next data enable register (NDER).
8. Select the ITU compare match that will be the TPC output trigger using the TPC output control
9. Set the next TPC output value in NDR.
10. Set 1 in the STR bit of the timer start register (TSTR) and start the timer counter.
11. Set the next output value in NDR whenever an IMIA interrupt is generated.
