16.5.2.6.9 PCI Source Synchronized to EOC, Edge Modes

When the PCI acceptance logic is operated in the Rising Edge or Any Edge modes and PSYNC = 1, the PCI source is synchronized to the EOC event, as shown in Figure 16-26. If an edge event is detected, the pulse is delayed until the next EOC event. In the case that a PCI source signal becomes active and then inactive within a single PWM cycle, the PCI active signal will not assert.
