REG3
Regulator Phase Control. Set bit to 1 for the regulator to operate
W/R 180° out of phase with the oscillator, set bit to 0 for the regulator
to operate in phase with the oscillator.

Regulator Turn-On Delay Control. DELAY[2:0]=000 for no delay.
Other code to delay relationship: 001 for 2ms, 010 for 4ms, 011
for 8ms, 100 for 16ms, 101 for 32ms, 110 for 64ms and 111 for
128ms. There is a propagation delay for about 100μs if selecting
no delay.

W/R
Regulator Power-OK Status. Value is 0 when the output is out of
regulation, value is 1 when the output is in regulation.

Note:
W/R: Write and read accessible. R: Read accessible, writing to the bit does not make change to the volume. WE/R: Write
and read accessible, write exact what it is before to avoid unexpected behavior. X is uncertain volume.
