Timed GPIO0 Event Counter Capture register 31_0 (TGPIOECCV0_31_0) – Offset 1238

Bit Range	Default	Access	Field Name and Description
31:0	0h	RO/V	Event Counter Capture Value [31:0] (ECCV) The value in this register must be the Timed GPIO event count associated with the time captured in the Time Capture Value register. A read to the Time Capture Value (TGPIOTCV0_31_0) register triggers HW to load the Event Counter value into this register. Note: The load signal is the same register read signal that returns the Time Capture Value to the SW. SW must first perform a read to the Time Capture Value (TGPIOTCV0_31_0) register, followed by a read to this Event Counter Capture Value (ECCV) register such that these two values are associated with each others, despite they are obtained thru 2 separate register read operations one after another. Note: Given that 64 bit values are in two registers, SW needs to account for roll over possibility

Event Counter Capture Value [31:0] (ECCV)

The value in this register must be the Timed GPIO event count associated with

the time captured in the Time Capture Value register.

A read to the Time Capture Value (TGPIOTCV0_31_0) register triggers HW to load the Event Counter value into this register.

Note: The load signal is the same register read signal that returns the Time Capture Value to the SW.

SW must first perform a read to the Time Capture Value (TGPIOTCV0_31_0) register, followed by a read to this Event Counter Capture Value (ECCV) register such that these two values are associated with each others, despite they are obtained thru 2 separate register read operations one after another.
