eCAP modules can be synchronized with each other by selecting a common SYNCIN source. SYNCIN source for eCAP can be either software sync-in or external sync-in. The external sync-in signal can come from eCAP, X-Bar or EPWM. The SWSYNC of the eCAP module is logical ORed with the SYNC signal as shown in Figure 21-7. The SYNC signal is defined by the selection of ECAPxSYNCINSEL[SEL] as shown in Figure 21-8.
