Bits
Description
1
Reload/Add B (RELOAD_ADD_B)
This bit determines the course of action when a Clock Target compare event
for Clock Event Channel B occurs.
When set, the 1588 Clock Target x Seconds Register (1588_CLOCK_TAR-
GET_SEC_x) and 1588 Clock Target x NanoSeconds Register
(1588_CLOCK_TARGET_NS_x) are loaded from the 1588 Clock Target x
Reload / Add Seconds Register (1588_CLOCK_TARGET_RELOAD_SEC_x)
and 1588 Clock Target x Reload / Add NanoSeconds Register
(1588_CLOCK_TARGET_RELOAD_NS_x) x=B.
When low, the Clock Target Registers are incremented by the Clock Target
Reload Registers.
0: Increment upon a clock target compare event
1: Reload upon a clock target compare event
0
Reload/Add A (RELOAD_ADD_A)
This bit determines the course of action when a Clock Target compare event
for Clock Event Channel A occurs.
When set, the 1588 Clock Target x Seconds Register (1588_CLOCK_TAR-
GET_SEC_x) and 1588 Clock Target x NanoSeconds Register
(1588_CLOCK_TARGET_NS_x) are loaded from the 1588 Clock Target x
Reload / Add Seconds Register (1588_CLOCK_TARGET_RELOAD_SEC_x)
and 1588 Clock Target x Reload / Add NanoSeconds Register
(1588_CLOCK_TARGET_RELOAD_NS_x) x=A.
When low, the Clock Target Registers are incremented by the Clock Target
Reload Registers.
0: Increment upon a clock target compare event
1: Reload upon a clock target compare event
