ACCUM CONFIG (25H) REGISTER

R/W-0

ACC1_CONFIG[1:0]

ACC2_CONFIG[1:0]

ACC3_CONFIG[1:0]

ACC4_CONFIG[1:0]

bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

This register is used to configure the Accumulator for one of the alternate modes: VSENSE Accumulation (Coulomb

Counting) or VBUS Accumulation (VBUS integration). All bits default to zero, which is the VPOWER Accumulation mode

for the Accumulator, useful for energy measurements.

bit 7-6

ACC1_CONFIG[1:0]: Configure the accumulator for Channel 1 to accumulate VPOWER (default),

VSENSE or VBUS.

00 = Channel 1 Accumulator accumulates VPOWER

01 = Channel 1 Accumulator accumulates VSENSE

10 = Channel 1 Accumulator accumulates VBUS

11 = Reserved, read as ‘0’.

bit 5-4

ACC2_CONFIG[1:0]: Configure the accumulator for Channel 2 to accumulate VPOWER (default),

VSENSE or VBUS.

00 = Channel 2 Accumulator accumulates VPOWER

01 = Channel 2 Accumulator accumulates VSENSE

10 = Channel 2 Accumulator accumulates VBUS

11 = Reserved, read as ‘0’.

bit 3-2

ACC3_CONFIG[1:0]: Configure the accumulator for Channel 3 to accumulate VPOWER (default),

VSENSE or VBUS.

00 = Channel 3 Accumulator accumulates VPOWER

01 = Channel 3 Accumulator accumulates VSENSE

10 = Channel 3 Accumulator accumulates VBUS

11 = Reserved, read as ‘0’.

bit 1-0

ACC4_CONFIG[1:0]: Configure the accumulator for Channel 4 to accumulate VPOWER (default),

VSENSE or VBUS.

00 = Channel 4 Accumulator accumulates VPOWER

01 = Channel 4 Accumulator accumulates VSENSE

10 = Channel 4 Accumulator accumulates VBUS

11 = Reserved, read as ‘0’.
