Bit Descriptions
RST:
Reset Bit
Bit 15
Setting this bit to '1' generates a system reset that is the same as power-on reset. Resets all registers to default
values; this bit self-clears.
BRNG:
Bus Voltage Range
Bit 13
0 = 16-V FSR
1 = 32-V FSR (default value)
PG:
PGA (Shunt Voltage Only)
Bits 11, 12
Sets PGA gain and range. Note that the PGA defaults to ÷8 (320-mV range). Table 5 shows the gain and range for
the various product gain settings.

BADC:
BADC Bus ADC Resolution/Averaging
Bits 7–10
These bits adjust the Bus ADC resolution (9-, 10-, 11-, or 12-bit) or set the number of samples used when
averaging results for the Bus Voltage Register (02h).
