There are four modes of operation for the sync signals: cyclic mode, single shot mode, cyclic with acknowledge mode, and single shot with acknowledge mode. Figure 6-265 shows examples of these modes. The start time is set by the IEP_SYNC_START_REG[31-0] SYNC_START bit field. The cycle time is configured by the IEP_SYNC0_PERIOD_REG[31-0] SYNC0_PERIOD bit field. The pulse length is defined by IEP_SYNC_PWIDTH_REG[31-0] SYNC_HPW bit field.
In SYNC1 dependent mode (IEP_SYNC_CTRL_REG[8] SYNC1_IND_EN = 0h), SYNC1 depends on SYNC0 and the start time of the SYNC1 can be defined by the IEP_SYNC1_DELAY_REG register. Figure 6-266 shows different examples when changing the value in the IEP_SYNC1_DELAY_REG register. Note: If the SYNC1 delay time is 0, SYNC1 reflects SYNC0. Cyclic generation cannot be used for network time synchronized applications because only the CMP1/CMP2 hit occurs in the compensated time domain.
