Clock Target Reload Low (CLOCK_TARGET_RELOAD_LO)
This field contains the low 32-bits of the 64-bit 1588 Clock Target Reload
value that is reloaded to the 1588 Clock Compare value. Alternatively, these
32-bits are added to the 1588 Clock Compare value when configured
accordingly.
1588 Clock Target Reload/Add Low-DWORD Register (1588_CLOCK_TARGET_RELOAD_LO)
This read/write register combined with
(1588_CLOCK_TARGET_RELOAD_HI)
Clock Target Reload is the value that is reloaded or added to the 1588 Clock Compare value when a
clock compare event occurs. Whether this value is reloaded or added is determined by the
