condition (S) from the I
slave addresses available. All PCF85132 with the corresponding SA0 level acknowledge
in parallel to the slave address, but all PCF85132 with the alternative SA0 level ignore the
whole I
After acknowledgement, a control byte follows which defines if the next byte is RAM or
command information. The control byte also defines if the next byte is a control byte or
further RAM or command data.
