RW | 0x1 |
0 | bwadjen | If set to 1, the Loop Bandwidth Adjust value comes from the Loop Bandwidth Adjust field. If set to 0, the Loop Bandwidth Adjust value equals the M field divided by 2 value of the VCO Control Register. The M divided by 2 is the upper 12 bits (12:1) of the M field in the VCO register. |
