Register descriptions
Table 8
details the assigned bit functions for the fifteen SC16C750 internal registers.
The assigned bit functions are more fully defined in
Section 7.1
through
Section 7.11
.

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.
Enhanced Feature Register is accessible only when LCR is set to ‘BF
Hex
’.
