11.2 Control(): 0x00/0x01
Issuing a Control() (or Manufacturer Access Control or MAC) command requires a 2-byte subcommand.
The subcommand specifies the particular MAC function desired. The Control() command enables the
system to control specific features of the gas gauge during normal operation and additional features when
the device is in different access modes, as described below. On this device, Control() commands may
also be sent to ManufacturerAccessControl().
Any subcommand that has a data response will be read back on MACData(). Reading the Control()
registers will always report the CONTROL_STATUS() data field, except after the DEVICE_TYPE() and
FW_VERSION() subcommands. After these subcommands, CONTROL_STATUS() will report the value
0xFFA5 one time before reverting to the normal data response. This is a flag to indicate that the data
response has been moved to MACData(). Writing a 0x0000 to Control() is not necessary to read the
CONTROL_STATUS(); however, doing so is okay.
