Data Shift Register (S1DAT)
S1DAT contains the serial data to be transmitted or data which has just been received. The MSB (bit 7) is transmitted or
received first; i.e. data shifted from right to left.

Data Shift Register (SFR address DAH)
15.4
Address Register (S1ADR)
This 8-bit register may be loaded with the 7-bit slave address to which the controller will respond when programmed as
a slave receiver/transmitter.

GC
This bit is used to determine whether the general call address is recognized. When
GC = 0, the general call address is not recognized; when GC = 1, the general call
address is recognized.
