Register descriptions
Table 8
details the assigned bit functions for the fifteen SC16C750B internal registers. The
assigned bit functions are more fully defined in
Section 7.1
through
Section 7.10
.
[1]
The value shown represents the register’s initialized HEX value; X = n/a.
[2]
These registers are accessible only when LCR[7] = 0.
[3]
The Special Register set is accessible only when LCR[7] is set to a logic 1.
