Table 71
Bits with a write direction (W in column Dir) are written by the MPU into configuration RAM. Typically, they are initially stored in flash memory and
copied to the configuration RAM by the MPU. Some of the more frequently programmed bits are mapped to the MPU SFR memory space. The
remaining bits are mapped to the address space 0x2XXX. Bits with R (read) direction can be read by the MPU. Columns labeled Rst and Wk
describe the bit values upon reset and wake, respectively. No entry in one of these columns means the bit is either read-only or is powered by the
NV supply and is not initialized. Write-only bits return zero when they are read.
Locations that are shaded in grey are non-volatile (i.e., battery-backed).

Description
Enables ADC and VREF. When disabled, reduces bias current.
ADC_DIV controls the rate of the ADC and FIR clocks.
The ADC_DIV setting determines whether MCK is divided by 4 or 8:
The resulting ADC and FIR clock is as shown below.
Connects a 100 µA load to the battery selected by TEMP_BSEL.
The result of the battery measurement.
