Module: GPIO_USER_CONTROL
Configures the controls of the GPIO .
GPIO_USER_CONTROL.GPIO0_TO_7_OUT
Write these bits to define the level on a GPIO output pin when configured for user output control.
STATUS.DPLL7_PHASE_PULL_IN_STATUS Bit Field Descriptions
Bit Field Name Field Type Default Value Description
REMAINING_TIME[7:0] R/O 0 Unsigned 8-bit phase pull-in time to finish in seconds.
If the value of this field < 255, the actual remaining time is between
(remaining_time) and (remaining_time + 1) seconds. If the value = 255, it
implies the actual remaining time >= 255 seconds.
