Section 10 Advanced Timer Unit (ATU)
Sample Setup Procedure for Interval Timer Operation: An example of the setup procedure for
interval timer operation is shown in figure 10.50.
1. Set the first-stage counter clock ' in prescaler register 1 (PSCR1).
2. Set the ITVE0–ITVE3 bit to be used in the interval interrupt request register (ITVRR) to 1. An
3. Set bit 0 to 1 in the timer start register (TSTR) to start TCNT0.
Note: TCNT0 bit 10 corresponds to ITVE0 and ITVAD0, bit 11 to ITVE1 and ITVAD1, bit 12

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 ITVAD0–ITVAD3 bit to be used in ITVRR to 1.
to ITVE2 and ITVAD2, and bit 13 to ITVE3 and ITVAD3.
