15.2 Format of Option Byte
15.2.1
220
Format of option bytes is shown below.
Caution The setting of this option is valid only when the crystal/ceramic oscillation clock is selected
Caution Because the option byte is referenced after reset release, if a low level is input to the RESET
Caution Because the X1 and X2 pins are also used as the P23/ANI3 and P22/ANI2 pins, the conditions

The X1 and X2 pins cannot be used as I/O port pins or analog input pins of A/D converter
because they are used as clock input pins.
Because the X1 pin is used as an external clock input pin, P23/ANI3 cannot be used as
an I/O port pin or an analog input pin of A/D converter.
P23/ANI3 and P22/ANI2 pins can be used as I/O port pins or analog input pins of A/D
converter.

RESET pin is used as is.
RESET pin is used as input port pin (P34).
