Remark
Caution Because the option byte is referenced after reset release, if a low level is input to the RESET
Caution Because the EXCLK pin is also used as the P23 pin, the condition under which the EXCLK

When used as an input-only port (P34), the setting of the on-chip pull-up resistor can be done
by PU34 on PU3 register.
pin can be used differ depending on the selected system clock source.
(1) External clock input is selected
(2) High-speed internal oscillation clock is selected
When used as RESET pin, the pin can be left open by setting ENPU34 to "1".
: don’t care
Because the pin is used as an external clock input pin, P23 cannot be used as an I/O port
pin.
P23 pin can be used as an I/O port pin.
