11.6.16 Event Capture Read Status Register

Important: Since the event time stamps only have 2 bits representing seconds, this register must be read while the oldest time stamp can still be calculated from the captured wall clock.

Name:	ECRDSTS
Address:	0x0204

Contains the status of all of the event capture data registers since the last time this register was read. Any time that this register is read, the current state, including wall clock time, is saved and can be read from the following event capture registers.
