7 Serial Communications Interface
The SCI, a universal asynchronous receiver transmitter (UART) serial communications interface, is one
of two independent serial I/O subsystems in M68HC11 K-series MCUs. Rearranging registers and con-
trol bits used in previous M68HC11 family devices has enhanced the existing SCI system and added
new features, which include the following:
A 13-bit modulus prescaler that allows greater baud rate control
A new idle mode detect, independent of preceding serial data
A receiver active flag
Hardware parity for both transmitter and receiver
The enhanced baud rate generator is shown in the following diagram. Refer to
Table 7

ues.
