15.2 Format of Option Byte
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
