One of my customers uses the ADuCM330 in slave mode, she wants to communicate under certain circumstances without any request from master.
Initial state : Master sleep / Slave(ADuCM330) sleep
The slave periodically checks the battery voltage and enters sleep mode again if it is normal.
if the battery voltage is below the reference voltage while sensing the battery voltage, she wants to send a critical alarm even if there is no master request.
In this state, since the master is in sleep mode, it wakes up with a signal from the slave.
I think that it will be possible to connect the communication by generating the interruption when the battery voltage is below the reference voltage while sensing the voltage, but please advise about the specific method.
(sample code etc.)
