The SSI11 pin is available only in 78K0/KA2-L (25, 32-pin products) and 78K0/KC2-L(48-pin products).

Bit 0 is a read-only bit.
78K0/KA2-L (25, 32-pin products) and 78K0/KC2-L(48-pin products) only. For the products of the other
than 78K0/KA2-L (25, 32-pin products) and 78K0/KC2-L(48-pin products), be sure to clear to 0.
To use P62/SO11, P60/SCK11/SCLA0, and P42/SSI11/PCL/INTP6 as general-purpose ports when
CSISEL = 0, set CSIM11 in the default status (00H).
To use P120/SO11/INTP0/EXLVI, P40/SCK11/RTCCL/RTCDIV, and P42/SSI11/PCL/INTP6 as general-
purpose ports when CSISEL = 1, set CSIM11 in the default status (00H).
To use P37/SO11, P35/SCK11, and P02/SSI11/INTP5 as general-purpose ports when CSISEL = 1, set
CSIM11 in the default status (00H).
Bit 0 (CSOT11) of CSIM11 and serial I/O shift register 11 (SIO11) are reset.
Do not rewrite TRMD11 when CSOT11 = 1 (during serial communication).
The SO11 output (refer to Figure 16-2) is fixed to the low level when TRMD11 is 0. Reception is started
when data is read from SIO11.
Do not rewrite SSE11 when CSOT11 = 1 (during serial communication).
Before setting this bit to 1, fix the SSI11 pin input level to 0 or 1.
Do not rewrite DIR11 when CSOT11 = 1 (during serial communication).
