8 PMPwrDownVch
In Partial Measurement Mode the V0/V1/V2 analog channel can be powered off to save power
0: Power on
1: Power off
This feature can be used when voltage measurement is not required in partial mode.
3
ACTRL_CLK_G
ATE
Power off the clock of analog control block to save power.
0: Power on
1: Power off
2
DSP_CLK_GAT
E
Power off the clock of DSP register to save power.
0: Power on
1: Power off
1
MTMS_CLK_GA
TE
Power off the metering and measuring block to save power.
0: Power on
1: Power off
0 PMClkLow
In Partial Measurement Mode the main clock can be reduced to 8.192MHz to save power.
0: 16.384MHz
1: 8.192MHz
In this low rate mode, the SPI interface only support half the access rate at normal mode.
Address: 0FH
Type: Read/Write
Default Value: 0000H

The WARN state can be ORed to IRQ0 output
0: normal
1: ORed
0IRQ1_OR
The IRQ1 state can be ORed to IRQ0 output
0: normal
1: ORed
