Register descriptions
Table 6
details the assigned bit functions for the SC16C2552 internal registers. The
assigned bit functions are further defined in
Section 7.1
through
Section 7.11
.
[1]
[2]
The value shown in represents the register’s initialized HEX value; X = n/a.
The General Register sets are accessible only when CS is a logic 0 and LCR[7] is a logic 0. Set A is accessible when CHSEL is a
logic 1, and set is accessible when CHSEL is a logic 0.
The Baud Rate register and AFR register sets are accessible only when CS is a logic 0 and LCR[7] is a logic 1 for the register set (A/B)
being accessed.
