Lock Enable GPIO 8 (LOCK_GPIO_8)
This bit enables/disables the GPIO 8 lock. This lock prevents a 1588 capture
from overwriting the Clock value if the 1588_GPIO8 interrupt in the
Interrupt Status and Enable Register (1588_INT_STS_EN)
due to a previous capture.
0: Disables GPIO 8 Lock
1: Enables GPIO 8 Lock
GPIO 9 Clock Event Mode (GPIO_EVENT_9)
These bits determine the output on GPIO 9 when a clock target compare
event occurs.
00: 100ns pulse output
01: Toggle output
10: 1588_TIMER_INT bit value in the 1588_INT_STS_EN register output

Reload/Add (RELOAD_ADD)
This bit determines the course of action when a clock target compare event
occurs. When set, the

Reload High-DWORD Register (1588_CLOCK_TARGET_RELOAD_HI)
1588 Clock Target Reload/Add Low-DWORD Register
(1588_CLOCK_TARGET_RELOAD_LO)
occurs. When low, the Clock Target Low and High Registers are
incremented by the Clock Target Reload Low Register when a clock target
compare event occurs.
0: Reload upon a clock target compare event
1: Increment upon a clock target compare event
