General Call Address is distinguished from a START byte by the value of the RD bit 
(RD = 0 for General Call Address, 1 for START byte).
RD—Read
This bit indicates the direction of transfer of the data. It is set when the Master is reading
data from the Slave. This bit matches the least-significant bit of the address byte after the
START condition occurs (for both Master and Slave modes). This bit clears when IEN = 0
and is updated following the first address byte of each transaction.

This bit is set when the I
