EGISTER
(S1DAT)
This register contains the serial data to be transmitted or data which has been received. Bit 7 is transmitted or received
first; i.e. data is shifted from right to left.

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.
