15.3.8
SCBRR is an 8-bit register that, together with the baud rate generator clock source selected by the
CKS[1:0] bits in the serial mode register (SCSMR), determines 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:
• Clocked synchronous mode:
B: Bit rate (bits/s)
N: SCBRR setting for baud rate generator (0 ≤ N ≤ 255)
Pφ: Operating frequency for peripheral modules (MHz)
n: Baud rate generator clock source (n = 0, 1, 2, 3) (for the clock sources and values of n,
(The setting must satisfy the electrical characteristics.)
