11. OPTION BYTES
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.
11.1 User option byte (000C0H to 000C2H/010C0H to 010C2H)
11.2 On-chip debug option byte (000C3H/ 010C3H)
Addresses 000C0H to 000C3H of the flash memory of the 78K0R/KF3 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 function
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
Caution Set the same value as 000C0H to 010C0H when the boot swap operation is used because
Caution Set the same value as 000C1H to 010C1H when the boot swap operation is used because
Caution Set FFH to 010C2H when the boot swap operation is used because 000C2H is replaced by
Caution Set the same value as 000C3H to 010C3H when the boot swap operation is used because
Operation of watchdog timer
