Description
1
1588 Timer Interrupt B (1588_TIMER_INT_B)
This interrupt indicates that the 1588 clock equaled or passed the Clock
Event Channel B Clock Target value in the 1588 Clock Target x Seconds
Register (1588_CLOCK_TARGET_SEC_x) and 1588 Clock Target x Nano-
Seconds Register (1588_CLOCK_TARGET_NS_x) x=B.
Note:
This bit is also cleared by an active edge on a GPIO if enabled.
For the clear function, GPIO inputs are edge sensitive and must be
active for greater than 40 ns to be recognized as a clear input.
0
1588 Timer Interrupt A (1588_TIMER_INT_A)

Event Channel A Clock Target value in the 1588 Clock Target x Seconds
Register (1588_CLOCK_TARGET_SEC_x) and 1588 Clock Target x Nano-
Seconds Register (1588_CLOCK_TARGET_NS_x) x=A.
Note:
This bit is also cleared by an active edge on a GPIO if enabled.
For the clear function, GPIO inputs are edge sensitive and must be
active for greater than 40 ns to be recognized as a clear input.
