REFRESH_G COMMAND (ADDRESS 1EH)

SEND

No Data in this command, Send Byte only

bit 7

bit 0

Legend:

R = Readable bit

W = Writeable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7-0

This command is a SEND Byte, does not contain any data. It is exactly like the REFRESH command

but is intended for use with the General Call command.

When it is sent to the device, the REFRESH command is executed and the readable accumulator data,

readable accumulator count, VBUS, and VSENSE measurements are all refreshed and the internal

accumulators values or accumulator count are reset, exactly like the REFRESH command. The master

can read the updated data 1 ms after the REFRESH_G command is sent, and anytime after than up

until the next REFRESH, REFRESH_G, or REFRESH_V command is sent.

REFRESH_V COMMAND (ADDRESS 1FH)

SEND

No Data in this command, Send Byte only

bit 7

bit 0

Legend:

R = Readable bit

W = Writeable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7-0

This command is a SEND Byte, does not contain any data. When it is sent to the device, the

REFRESH_V command is executed.

It is similar to the REFRESH command except the accumulators and accumulator count are not reset.

The readable accumulator data, readable accumulator count, VBUS, and VSENSE measurements are all

refreshed without affecting the internal accumulators values or accumulator count. The master can read

the updated data 1 ms after the REFRESH_V command is sent, and anytime after than up until the next

REFRESH, REFRESH_G, or REFRESH_V command is sent.
