Section 15 Serial Communication Interface with FIFO (SCIF)
15.3.8
SCBRR is an 8-bit register that is used with the CKS1 and CKS0 bits in the serial mode register
(SCSMR) and the BGDM and ABCS bits in the serial extension mode register (SCEMR) to
determine the serial transmit/receive bit rate.
The CPU can always read and write to SCBRR. SCBRR is initialized to H'FF by a power-on reset.
Each channel has independent baud rate generator control, so different values can be set in three
channels.
The SCBRR setting is calculated as follows:
• Asynchronous mode:

REJ09B0313-0300
When baud rate generator operates in normal mode (when the BGDM bit of SCEMR is 0):
When baud rate generator operates in double speed mode (when the BGDM bit of
SCEMR is 1):
