Bit 0 is a read-only bit.
To use P02/SO11, P04/SCK11, and P05/SSI11/TI001 as general-purpose ports, 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 (see 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).
