PMON_CONFIG
Code: 0xD4, read/write byte. Value after reset: 0xAF.
Modifying the power monitor settings while the power monitor is sampling is not supported. The power monitor must be stopped before
any setting in Table 38 is changed to ensure correct operation and to prevent the generation of any potential spurious data and status alerts.

Description
Always reads as 0000.
Returns the peak VOUT voltage since the register was last cleared.
Description
Always reads as 0000000.
Power monitor is not running.
Default. Start the sampling of current and voltage with the power monitor. In single shot
mode, this bit clears itself after one complete cycle. In continuous mode, this bit must
be written to 0 to stop sampling.
Description
This setting selects single shot sampling mode.
Default. This setting selects continuous sampling mode.
Default. The power monitor samples the input voltage on the SENSE+ pin and IOUT.
The power monitor samples the input voltage on the SENSE+ pin, IOUT, and the
voltage on the VOUT pin.
Sets the voltage input range from 0 V to 6 V (low input voltage range).
Default. Sets the voltage input range from 0 V to 20 V (high input voltage range).
Reserved. This bit must always be written as 0.
Default. This bit must be set to 1 for the power monitor current sense to operate
correctly.
Disables sample averaging for current and voltage.
Sets sample averaging for current and voltage to two samples.
Sets sample averaging for current and voltage to four samples.
Sets sample averaging for current and voltage to eight samples.
Sets sample averaging for current and voltage to 16 samples.
Sets sample averaging for current and voltage to 32 samples.
Sets sample averaging for current and voltage to 64 samples.
Default. Sets sample averaging for current and voltage to 128 samples.
