23.1 Functions of Option Bytes
function is set. When using the product, be sure to set the following functions by using the option bytes.
Therefore, set the same values as 000C0H to 000C3H to 010C0H to 010C3H.
23.1.1 User option byte (000C0H to 000C2H/010C0H to 010C2H)
Addresses 000C0H to 000C3H of the flash memory of the 78K0R/Ix3 form an option byte area.
Option bytes consist of user option byte (000C0H to 000C2H) and on-chip debug option byte (000C3H).
Upon power application or resetting and starting, an option byte is automatically referenced and a specified
To use the boot swap operation during self programming, 000C0H to 000C3H are replaced by 010C0H to 010C3H.
Caution Be sure to set FFH to 000C2H (000C2H/010C2H when the boot swap operation is used).
(1) 000C0H/010C0H
(2) 000C1H/010C1H
(3) 000C2H/010C2H
