Register descriptions
Table 9
details the assigned bit functions for the SC16C652B internal registers. The
assigned bit functions are more fully defined in
Section 7.1
through
Section 7.11
.
[1]
The value shown in represents the register’s initialized HEX value; X = not applicable.
[2]
This bit is only accessible when EFR[4] is set.
[3]
Accessible only when LCR[7] is logic 0.
[4]
Baud rate registers accessible only when LCR[7] is logic 1.
[5]
Enhanced Feature Register, Xon1/Xon2 and Xoff1/Xoff2 are accessible only when LCR is set to ‘BFh’.
