Address: $0071
The six addressable registers in the SCI are:
Throughout this manual, the registers are discussed by function. In the
event that not all bits in a register are referenced, the bits that are not
discussed are shaded.
This register selects the 13-bit divisor shown in
the SCI baud rate. (See
during initialization, but it can be changed at any time.
