Description
Setting this bit disables the OUTAUX output.
Setting this bit disables the SR2 output.
Setting this bit disables the SR1 output.
Setting this bit disables the OUTD output.
Setting this bit disables the OUTC output.
Setting this bit disables the OUTB output.
Setting this bit disables the OUTA output.
Setting this bit disables the GATE output but does not affect the VSx feedback point.
Description
1 = negative gain is introduced.
0 = positive gain is introduced.
These bits set the gain trim for the ACSNS ADC.
Description
These bits determine the duration of the soft start ramp.

Setting this bit to 1 enables the soft start from precharge function. When this function is enabled,
the soft start ramp starts from the value of the voltage detected on VS1 or VS3± (depending on
the OrFET status).
