Table 128. Incremental Phase Offset Control
Address Bits Bit Name Description
0x0A0C [7:3] Unused
[2]
Reset phase offset
Resets the incremental phase offset to 0.
This is an autoclearing bit.
[1] Decr phase offset Decrements the incremental phase offset by the amount specified in the
incremental phase lock offset step size register (Register 0x0314 to Register 0x0315).
This is an autoclearing bit.
[0] Incr phase offset Increments the incremental phase offset by the amount specified in the
incremental phase lock offset step size register (Register 0x0314 to Register 0x0315).
This is an autoclearing bit.
