If SMB Configuration [FIXED_ADDR] is set (1), then the slave address is 0x16/0x17 and the ADREN
and SMBA pins are ignored and not used.
NOTE: When determining the values for SMBTAR_ADDR0...7, take into account the R/W bit by
programming all addresses to even numbers.

16.5 Broadcasts to Smart Charger and Smart Battery Host
If the [HPE] bit is enabled, MASTER mode broadcasts to the host address are PEC enabled. If the [CPE]
bit is enabled, MASTER mode broadcasts to the smart-charger address are PEC enabled. The [BCAST]
bit enables all broadcasts to a host or a smart charger. When the [BCAST] bit is enabled, the following
broadcasts are sent:
• ChargingVoltage() and ChargingCurrent() broadcasts are sent to the smart-charger device address
(Charger Address) periodically. The default period is set in Charger Request Timer.
• If any of the [OCA], [TCA], [OTA], [TDA], [RCA], [RTA] flags are set, the AlarmWarning() broadcast
is sent to the host device address (Host Address) at the period set in Alarm Timer. Broadcasts stop
when all flags above have been cleared.
• If any of the [OCA], [TCA], [OTA], [TDA] flags are set, the AlarmWarning() broadcast is sent to a
smart-charger device address (Charger Address) at the period set in Alarm Timer. Broadcasts stop
when all flags above have been cleared.
