Note:
When using P10 as a general-purpose port, set the Clock Control Register 3 (address 0212

) bit 7 to 1.
When using P10 as a clock control signal, refer to 8.14.1 oscillation control.
P10 becomes clock control signal output and “H” output setting immediately after reset release , and P16
becomes “L” output setting after reset release.
