Register descriptions
Table 7
details the assigned bit functions for the SC16C2550 internal registers. The
assigned bit functions are more fully defined in
Section 7.1
through
Section 7.11
.

[3]
[4]
The value shown in represents the register’s initialized HEX value; X = n/a.
Accessible only when LCR[7] is logic 0.
Baud rate registers accessible only when LCR[7] is logic 1.
Enhanced Feature Register, Xon-1,2 and Xoff-1,2 are accessible only when LCR is set to ‘BF
Hex
’.
Table 7:
Shaded bits are only accessible when EFR[4] is set.
