24.9.3 SI/O3, SI/O4
The SOUTi default value which is set to the SOUTi pin by the SMi7 bit approximately 10ns may be output
when changing the SMi3 bit from "0" (I/O port) to "1" (SOUTi output and CLK function) while the SMi2 bit
in the SiC (i=3 and 4) to "0" (SOUTi output) and the SMi6 bit is set to "1" (internal clock). And then the
SOUTi pin is held high-impedance.
If the level which is output from the SOUTi pin is a problem when changing the SMi3 bit from "0" to "1", set
the default value of the SOUTi pin by the SMi7 bit.
