At this moment master-transmitter
becomes master-receiver and

SMBALERT signal is released
(assuming that only one device
generated the alert)
If more than 3 bytes are read, the slave device loops back to the first byte (manufacturer byte) and keeps sending data until the
master generates a ‘No Acknowledge’.
