Baud Rate Generator
UART mode
I/O interface mode
Baud rate calculation to use the baud rate generator:
The baud rate generator generates transmit and receive clocks to determine the serial
channel transfer rate.
The baud rate generator uses either the φ T1, φ T4, φ T16 or φ T64 clock supplied from the
7-bit prescaler. This input clock selection is made by setting the baud rate generator control
register, SC0BRCR <BR0CK1:0>.
The baud rate generator contains built-in dividers for divide by 1, N + m/16 (N=2~15,
m=0~15), and 16. The division is performed according to the settings of the baud rate
generator control registers SC0BRCR <BR0ADDE> <BR0S3:0> and SC0BRADD
<BR0K3:0> to determine the resulting transfer rate.
divide by N, by setting SC0BRCR <BR0ADDE> to “0”.
The N + (16 - K)/16 division function cannot be used in the I/O interface mode. Be sure to

The highest baud rate out of the baud rate generator is 1.25 Mbps when φ T1 is 20 MHz.
The highest baud rate will be generated when φ T1 is 20 MHz. The divide ratio can be
set to 1 if double buffer is used and the resulting output baud rate will be 10 Mbps. (If
double buffering is not used, the highest baud rate will be 5.0 Mbps applying the divide
ratio of “2”).
If SC0BRCR <BR0ADDE> = 0,
The setting of SC0BRADD <BR0K3:0> is ignored and the counter is divided by N
where N is the value set to SC0BRCR <BR0S3:0>. (N = 1 to 16).
If SC0BRCR <BR0ADDE> = 1,
The N + (16 - K)/16 division function is enabled and the division is made by using the
values N (set in SC0BRCR <BR0S3:0>) and K (set in SC0BRADD<BR0K3:0>). (N = 2
to 15, K = 1 to 15)
The fsys frequency, which is independent of the baud rate generator, can be used as
the serial clock. In this case, the highest baud rate will be 2.5 Mbps when fsys is 40
MHz.
(Note) For the N values of 1 and 16, the above N+(16-K)/16 division function is

inhibited. So, be sure to set SC0BRCR<BR0ADDE> to “0.”
