<1> Low level input to the SSI11 pin
<2> High level input to the SSI11 pin
<3> Data is written to SOTB11 or data is read from SIO11 while a high level is input to the SSI11 pin, then a low
<4> A high level is input to the SSI11 pin during transmission/reception or reception
Remark n = 0:
In the 3-wire serial I/O mode, data is transmitted or received in 8-bit units. Each bit of the data is transmitted or
received in synchronization with the serial clock.
Data can be transmitted or received if bit 6 (TRMD1n) of serial operation mode register 1n (CSIM1n) is 1.
Transmission/reception is started when a value is written to transmit buffer register 1n (SOTB1n). In addition,
data can be received when bit 6 (TRMD1n) of serial operation mode register 1n (CSIM1n) is 0.
Reception is started when data is read from serial I/O shift register 1n (SIO1n).
However, communication is performed as follows if bit 5 (SSE11) of CSIM11 is 1 when serial interface CSI11 is in
the slave mode.
After communication has been started, bit 0 (CSOT1n) of CSIM1n is set to 1. When communication of 8-bit data
has been completed, a communication completion interrupt request flag (CSIIF1n) is set, and CSOT1n is cleared
to 0. Then the next communication is enabled.
Cautions 1. Do not access the control register and data register when CSOT1n = 1 (during serial
→ Transmission/reception is started when SOTB11 is written, or reception is started when SIO11 is read.
→ Transmission/reception or reception is held, therefore, even if SOTB11 is written or SIO11 is read,
level is input to the SSI11 pin
→ Transmission/reception or reception is started.
→ Transmission/reception or reception is suspended.
transmission/reception or reception will not be started.
2. When using serial interface CSI11, wait for the duration of at least one clock before the

communication).
clock operation is started to change the level of the SSI11 pin in the slave mode; otherwise,
malfunctioning may occur.
