Sample Setup Procedure for Interval Timer Operation: An example of the setup procedure for

interval timer operation is shown in figure 10.58.

1. Set the first-stage counter clock ø' in prescaler register 1 (PSCR1).

2. Set the ITVE bit to be used in the interval interrupt request register (ITVRR) to 1. An interrupt

request can be sent to the CPU when the corresponding bit changes to 1 in the channel 0 free-

running counter (TCNT0).

To start A/D converter sampling, set the ITVA bit to be used in ITVRR to 1.

3. Set bit 0 to 1 in the timer start register (TSTR) to start TCNT0.
