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

R/W

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
