14 - SERIAL CHANNELS
Serial communication with other microcontrollers,
processors, terminals or external peripheral com-
ponents is provided by two serial interfaces: the
asynchronous / synchronous serial channel
(ASC0) and the high-speed synchronous serial
channel (SSC).
Two dedicated Baud rate generators set up all
standard Baud rates without the requirement of
oscillator tuning. For transmission, reception and
erroneous reception, 3 separate interrupt vectors
are provided for each serial channel.
ASC0
ASC0 supports full-duplex asynchronous commu-
nication at up to 781.25K Baud and half-duplex

Baud Rate (Baud)
synchronous communication up to 5M Baud at
25MHz system clock.
For asynchronous operation, the Baud rate gener-
ator provides a clock with 16 times the rate of the
established Baud rate.
Table 18 lists various commonly used Baud rates
together with the required reload values and the
deviation errors compared to the intended
Baud rate.
For synchronous operation, the Baud rate genera-
tor provides a clock with 4 times the rate of the
established Baud rate.
