Permissible baud
rate range during
reception
Make sure that the baud rate error during reception is within the permissible
error range, by using the calculation expression shown below.

Do not access SOTB1n when CSOT1n = 1 (during serial communication).
p. 328
SOTB1n:
Transmit buffer
register 1n
The SSI11 pin can be used in the slave mode. For details of the
transmission/reception operation, see 15.4.2 (2) Communication operation.

Do not access SIO1n when CSOT1n = 1 (during serial communication).
p. 328
SIO1n: Serial I/O
shift register 1n
The SSI11 pin can be used in the slave mode. For details of the reception
operation, see 15.4.2 (2) Communication operation.

Hard
When the Ring-OSC clock is selected as the clock supplied to the CPU, the
clock of the Ring-OSC oscillator is divided and supplied as the serial clock. At
this time, the operation of serial interface CSI10 is not guaranteed.
p. 332
Do not write to CSIC10 while CSIE10 = 1 (operation enabled).
p. 332
Clear CKP10 to 0 to use P10/SCK10/TxD0, P11/SI10/RxD0, and P12/SO10 as
general-purpose port pins.

When the Ring-OSC clock is selected as the clock supplied to the CPU, the
clock of the Ring-OSC oscillator is divided and supplied as the serial clock. At
this time, the operation of serial interface CSI11 is not guaranteed.
p. 333
Do not write to CSIC11 while CSIE11 = 1 (operation enabled).
p. 333
Clear CKP11 to 0 to use P02/SO11, P03/SI11, and P04/SCK11 as general-
purpose port pins.
p. 333
CSIC11: Serial
clock selection
register 11
The phase type of the data clock is type 1 after reset.

3-wire serial I/O
mode
Take relationship with the other party of communication when setting the port
mode register and port register.
p. 336
Do not access the control register and data register when CSOT1n = 1 (during
serial communication).
p. 339
Communication
operation
When using serial interface CSI11, wait for the duration of at least one clock
before the clock operation is started to change the level of the SSI11 pin in the
slave mode; otherwise, malfunctioning may occur.
