In this case data capture is enabled for 2 PIC cycles every P PIC cycles where P is computed from the Time-base Expansion Register R13 according to:
P = 19 + 3 * (TB + 1)where:
The minimum time-base expansion period is 10.0 uS and the maximum 316 uS. This provides expanded time-base sample rates ranging from 3.165 kHz to 100 kHz. At all expanded time-base rates, 20 samples are acquired in a single burst at 25 MHz at each expanded time-base cycle.The pre trigger delay and post trigger delay are calculated the same way as trace mode TM2 except the expanded time-base period P above is used.
