22.1 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.
22.1.1 User option byte (000C0H to 000C2H/010C0H to 010C2H)
Addresses 000C0H to 000C3H of the flash memory of the 78K0R/KE3 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
Operation of watchdog timer
• Operation is stopped or enabled in the HALT or STOP mode.
Setting of interval time of watchdog timer
Operation of watchdog timer
• Operation is stopped or enabled.
Setting of window open period of watchdog timer
Setting of interval interrupt of watchdog timer
• Used or not used
Caution Set the same value as 000C0H to 010C0H when the boot swap operation is used because
Setting of LVI upon reset release (upon power application)
• LVI is ON or OFF by default upon reset release (reset by RESET pin excluding LVI, POC, WDT, or illegal
Caution Set the same value as 000C1H to 010C1H when the boot swap operation is used because
Be sure to set FFH, as these addresses are reserved areas.
Caution Set FFH to 010C2H when the boot swap operation is used because 000C2H is replaced by
