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 contains an image of Register 7-19 and reflects the current active values of these settings, whereas the

values in register 25h may be programmed but not activated by one of the REFRESH commands. This register

allows software to determine the actual active settings.

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’.
