Polarity setting for input

voltage compensation

R/W

Setting this bit applies an offset on the input voltage reading, READ_VIN, based on the reading

of the input current, READ_IIN. The compensation multipler is set in Register 0xFE59. It is used

to compensate the voltage drop caused by the current conduction.

0 = positive polarity compensation.

1 = negative polarity compensation.

Input voltage

compensation multiplier

R/W

These bits specify the multiplier, N, for the input voltage compensation coefficient. The

compensation equation is N × (Register 0xFEA7[15:4] value) ÷ 211, and the result is added to

Frequency go

R/W

This bit synchronously latches the contents of Register 0x33 into the shadow registers used to

calculate the switching frequency. Reading of this bit always returns 1.

PWM setting go

R/W

This bit synchronously latches the contents of Registers 0xFE3E to Register 0xFE53 into the shadow

registers used to calculate the PWM edge timing. Reading this bit always returns 1.
