Load 45H into the S1 register; PCF8584
generates the repeated 'START condition' only.
The current contents of register S0 is NOT
clocked out onto the I
The next byte sent to register S0 should be the
'slave address'
Load 'slave address' into the S0 register. Once
loaded, it is automatically clocked out over the I
'Slave address' = slave address (7 bits)
