This counter provides the time-base for event captures, and is clocked via the system clock.
On any of the four event loads, an option to reset the 32-bit counter is given. This is useful for time difference capture. The 32-bit counter value is captured first, then it is reset to 0 by any of the LD1-LD4 signals.
The PRU-ICSS_eCAP_0 "SYNCIn" hardware event synchronization input and "SYNCOut" hardware synchronization output are NOT implemented in the PRU-ICSS. However, a software-forced synchronization via bit PRU-ICSS_ECAP_ECCTL2[8] SWSYNC, can be used as an alternative, provided that PRU-ICSS_ECAP_ECCTL2[5] SYNCI_EN bit is set to 0b1.
