(a) Baud rate
(b) Error of baud rate
The baud rate can be calculated by the following expression.
f
k:
The baud rate error can be calculated by the following expression.
Cautions 1. Keep the baud rate error during transmission to within the permissible error range at
XCLK6
Baud rate =
Error (%) =
Example: Frequency of base clock = 10 MHz = 10,000,000 Hz
: Frequency of base clock selected by TPS63 to TPS60 bits of CKSR6 register
Value set by MDL67 to MDL60 bits of BRGC6 register (k = 8, 9, 10, ..., 255)
2. Make sure that the baud rate error during reception satisfies the range shown in (4)
f
the reception destination.
Permissible baud rate range during reception.

XCLK6
Set value of MDL67 to MDL60 bits of BRGC6 register = 00100001B (k = 33)
Target baud rate = 153600 bps
Baud rate = 10 M/(2
Error = (151515/153600
