9.19.1 Automatic Power Stage Retry (AutoRetry)
Default = 1
Function:
Enables the Auto-Retry function upon over-current error. See “Automatic Power Stage Shut-Down” on
page 53.
AutoRetry Setting
Auto-Retry State
0 ..........................................Auto-Retry feature disabled.
1 ..........................................Auto-Retry feature enabled.
9.19.2 Select VD Level (SelectVD)
Default = 1
Function:
This bit selects between a VD of 2.5 V, 3.3 V, or 5.0 V.
SelectVD Setting
Selected VD Level
0 ..........................................VD = 2.5 V.
1 ..........................................VD = 3.3 V or 5.0 V.
9.19.3 Power Down ADC (PDnADC)
Default = 1
Function:
The ADC will enter a power down state when this bit is enabled.
PDnADC Setting
ADC Power-Down State
0 ..........................................Normal ADC operation.
1 ..........................................ADC power-down enabled.
9.19.4 Power Down PWM Power Output X (PDnOutX)
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
the channel output configuration selected. When transitioning from normal operation to power down, the
specific output will power down according to the state of the RmpSpd[1:0] bits and the channel output con-
figuration selected.
PDnChX Setting
Power Output X Power-Down State
0 ..........................................Normal power output X operation.
1 ..........................................Power output X power-down enabled.
The entire divide will enter a low-power state when this function is enabled:
