The data shift register 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.

The 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. The LSB (GC) is used to determine whether the
general call address is recognized.
