23. Usage Precaution
23.12.3 SI/Oi (i = 3 to 6) ⁽¹⁾
The SOUTi default value which is set to the SOUTi pin by the SMi7 in the SiC register bit approximately
10ns may be output when changing the SMi3 bit in the SiC register from “0” (I/O port) to “1” (SOUTi output
and CLKi function) while the SMi2 bit in the SiC register 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.
NOTE:
1. SI/O5 and SI/O6 are only in the 128-pin version.
