Default = 1
Function:
Enables the Auto-Retry function upon over-current error. See

Default = 1
Function:
Enables the PWM power output over-current protection feature described in
Shut-Down” on page
Default = 1
Function:
This bit selects between a VD of 2.5 V, 3.3 V, or 5.0 V.
Default = 1
Function:
The ADC will enter a power down state when this bit is enabled.
Default = 1
Function:
When set, the specific PWM power output will enter a power-down state. Only the output power stage is
powered down. The PWM modulator is not affected, nor is the setup or delay register values. When set
to normal operation, the specific output will power up according to the state of the RmpSpd[1:0] bits and
