Note
The BROADCAST mode feature is available in the latest firmware version in the BQ28Z610-R2
product folder on
TI.com : It is not included in the shipped version.
The following data flash parameters enable the configuration of the BROADCAST mode feature. This feature
is disabled by default because not all host MCU/CPUs are compatible with multi-master I
2
C operation, and
collisions could hang the host's comm engine.
