Register descriptions
Table 9
details the assigned bit functions for the fifteen SC16C550B internal registers.
The assigned bit functions are more fully defined in
Section 7.1
through
Section 7.10
.

The value shown represents the register’s initialized HEX value; X = n/a.
These registers are accessible only when LCR[7] = 0.
The Special Register set is accessible only when LCR[7] is set to a logic 1.
