X = Bit is unknown
This command is a Send Byte and does not contain any data.
It is intended for use with the General Call Address command. PAC1721 executes the Refresh_G command upon
reception. Accumulator data, accumulator count, VBUS and VSENSE measurements are all updated, while accumulator
and accumulator count are reset.
The host can read the updated data anytime following a Refresh_G command issued after a completed conversion
cycle and until the next Refresh (any) command is issued.
