Data Shift Register (S1DAT)
This register contains the serial data to be transmitted or data has just been received. Bit 7 is transmitted or received first.

Data Shift Register (DAH)
10.6
Slave 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
slave receiver/transmitter. The LSB bit (GC) is used to determine whether the general CALL address is recognized.
