The status of the SO1n output is as follows depending on the setting of CSIE1n, TRMD1n, DAP1n, and DIR1n.
Caution If a value is written to CSIE1n, TRMD1n, DAP1n, and DIR1n, the output value of SO1n

78K0/KC2-L:
The actual output of the SO10 or SO11 pin is determined according to the port mode register and
the port register corresponding to SO10 or SO11, as well as the SO1n output.
This is a status after reset.
To use the SO11 pin as general-purpose port, set CSIC11 in the default status (00H).
After transmission has been completed, the SO1n pin holds the output value of the last bit of
transmission data.
