1588 Clock Target Reload/Add Low-DWORD Register (1588_CLOCK_TARGET_RELOAD_LO)
Offset:
188h
Size:
32 bits
This read/write register combined with 1588 Clock Target Reload High-DWORD Register
(1588_CLOCK_TARGET_RELOAD_HI) form the 64-bit 1588 Clock Target Reload value. The 1588
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 Reload/Add
(RELOAD_ADD) bit of the 1588 Configuration Register (1588_CONFIG). Refer to Chapter 10, "IEEE
1588 Hardware Time Stamp Unit," on page 134 for additional information.
