DC-DC Converter Peak Current Monitor Calibration Status (Si3230 only).
Writing a one to this bit starts the dc-dc converter peak current monitor calibration rou-
tine.
0 = Normal operation.
1 = Calibration being performed.
Read returns zero.
DC-DC Converter Feed Forward Pin (DCFF) Polarity.
This read-only register bit indicates the polarity relationship of the DCFF pin to the
DCDRV pin. Two versions of the Si3230 are offered to support the two relationships.
0 = DCFF pin polarity is opposite of DCDRV pin (Si3230).
1 = DCFF pin polarity is same as DCDRV pin (Si3230M).
DC-DC Converter Minimum Off Time.
This register sets the minimum off time for the pulse width modulated dc-dc
converter control. T
