15.3.10 Bit Rate Register (SCBRR)
SCBRR is an 8-bit register that, together with the baud rate generator clock source selected by the
CKS1 and CKS0 bits in the serial mode register (SCSMR), determines the serial transmit/receive
bit rate.
The CPU can always read and write to SCBRR.
The SCBRR setting is calculated as follows:
• Asynchronous mode:
• Clock synchronous mode:
N =
N =
B:
N:
Pφ: Operating frequency for peripheral modules (MHz)
n:

Bit rate (bits/s)
SCBRR setting for baud rate generator (0 ≤ N ≤ 255)
(The setting value should satisfy the electrical characteristics.)
