G
UART mode
Transfer rate =
Input clock of baud rate generator
Frequency divisor of baud rate generator
G
I/O interface mode
Transfer rate =
Input clock of baud rate generator
Frequency divisor of baud rate generator
The relation between the input clock and the source clock (fc) is as follows:
φ
T0 =
fc/4
φ
T2 = fc/16
φ
T8 = fc/64
φ
T32 = fc/256
Accordingly, when source clock fc is 12.288 MHz, input clock is
φ
T2 (fc/16), and frequency divisor is 5, the transfer rate
in UART mode becomes as follows:
Transfer rate =
fc/16
5
= 12.288 x 10
6
/16/5/16 = 9600 (bps)
Table 3.11 (1) shows an example of the transfer rate in UART mode.
Also with 8-bit timer 0, the serial channel can get a transfer rate. Table 3.11 (2) shows an example of baud rate using
timer 0.
Table 3.11 (1) Selection of Transfer Rate (1) (When Baud Rate Generator is Used)
Note:
Transfer rate in I/O interface mode is 8 times as fast as the values given in the above table.

Baud Rate Generator
Baud rate generator comprises a circuit that gener-
ates transmission and receiving clocks to determine the
transfer rate of the serial channel.
The input clock to the baud rate generator,
φ
T0 (fc/
4),
φ
T2 (fc/16),
φ
T8 (fc/64), or
φ
T32 (fc/256) is generated
by the 9-bit prescaler which is shared by the timers. One
of these input clocks is selected by the baud rate genera-
tor control register BR0CR/BR1CR <BR0CK1, 0/
BR1CK1, 0>.
The baud rate generator includes a 4-bit frequency
divider, which divides frequency by 2 to 16 values to
determine the transfer rate.
How to calculate a transfer rate when the baud rate
generator is used is explained below.
