Lock 2
0x0 = max
0x3 = typical
0xF = min
Lock gain (power of 2)
0x0 = max

Period-2 in Free-running mode, in XCLKs
Duty cycle of PWM in XCLKs
Non-overlap of PWMs in XCLKs
In smooth change mode, the number of
cycles skipped before the period/duty
registers are incremented/decremented
The number of cycles per frame in frame
lock mode when not using the internally
generated cycles per frame from a previous
freerun mode
nd
order gain (power of 2)
