Referring to T12 input clock the counting sequence is defined by the following counting
rules:
T12 in edge-aligned mode:
• The counter is reset to zero and (if desired) the T12 shadow transfer takes place if the
T12 in center-aligned mode:
• The count direction is set to counting up (CDIR=’0’) if the one-match is detected while
• The count direction is set to counting down (CDIR=’1’) if the period-match is detected
• The counter counts up while CDIR=’0’ and it counts down while CDIR=’1’.
• If enabled the shadow transfer takes place:
• if the period-match is detected while counting up
• if the one-match is detected while counting down
The timer T12 prescaler is reset while T12 is not running to ensure reproducible timings
and delays.
The counting rules lead to the following sequences:
