How to calculate the transfer rate (when timer 2 is used0)
Input clock of timer 2
T1 = fc/8
T4 = fc/32
T16 = fc/128
Serial clock generation circuit
This circuit generates the basic clock for transmitting
and receiving data.
1) I/O interface mode
When in SCLK1 output mode with the setting of
SCCR1 <IOC1> = “0”, the basic clock will be gener-
ated by dividing by 2 the output of the baud rate gen-
erator described before. When in SCLK1 input mode
with the setting of SCCR1 <IOC1> = “1”, the rising
edge or the falling edge will be detected according to
the setting of SCCR1 <SCLK1> register to generate
the basic clock.
2) Asynchronous communication (UART) mode
According to the setting of SCMOD1 <SC11,01>, the
above baud rate generator clock, internal clock 1 (fc/
2) (312.5 Kbaud at 10MHz), or the match detect signal
from timer 2 will be selected to generate the basic clock
SIOCK.
Receiving counter
The receiving counter is a 4-bit binary counter used in
asynchronous communication (UART) mode and
counts up by SIOCLK1 clock. 16 pulses of SIOCLK1
are used for receiving 1 bit of data, and the data is
sampled three times at the 7th, 8th and 9th clock.
With the three samples, the received data is evaluated
by the rule of majority.
For example, if the sampled data is “1”, “0” and “1” at
7th, 8th and 9th clock, respectively, the received data
is evaluated as “1”. The sampled data “0”, “0”, and “1”
is evaluated that the received data is “0”.
Receiving control
1) I/O interface mode
When in SCLK1 output mode with the setting of
SCCR1 <IOC1> = “0”, RxD1 signal will be sampled at
the rising edge of shift clock which is output to SCLK
pin.
