Timed GPIO0 Event Counter Register 31_0 (TGPIOEC0_31_0) – Offset 1240
Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
31:0 | 0h | RO/V | Event Counter Register [31:0] (EC) Event Counter (EC):After Timed GPIO is enabled, event counter operates as follow: When Timed GPIO is configured as input, event counter will increment by 1 for every input event triggered. When Timed GPIO is configured as output, event counter will increment by 1 for every output event generated. Note: The signal to increment the count is the same signal that captures the ART time into the TCV register. For Timed GPIO configured as output with Periodic Mode enabled, it is also the same signal that updates the Comparator Value for the subsequent match.When Timed GPIO is disabled, event counter is reset to 0x0.Note: Given that 64 bit values are in two registers, SW needs to account for roll over possibility |
