â SOFTWARE RESET SEQUENCE OR COMMAND RETRY
In case the malfunction has occurred after power on, the master side stopped the I2C communication during
processing, or unexpected malfunction has occurred, execute the following (1) software recovery sequence
just before each command, or (2) retry command just after failure of each command.
(1) Software Reset Sequence
Since the slave side may be outputting âLâ level, do not force to drive âHâ level, when the master side drives
the SDA port. This is for preventing a bus conflict. The additional hardware is not necessary for this software
reset sequence.
