16.5.2.6.12 PCI Terminator Synchronized to EOC

By default, the PCI logic synchronizes a terminator event to the PWM EOC. This allows the PWM to resume cleanly at the start of a new cycle. The rising edge of the terminating signal is held off until the occurrence of the EOC event. The terminator signal is usually a pulse event used to reset the latched state of the PCI logic. If a short pulse is received prior to the occurrence of an EOC event, a Reset pulse is produced at the next EOC event. If the terminator signal is a longer pulse, the synchronized output is held active for as long as the terminator signal is present. This behavior can be used to force the PCI logic to a Reset state, if desired. Terminator event synchronization timing is shown in Figure 16-29.
