24.1 Functions of Option Bytes
turned on or when the device is restarted from the reset status, the device automatically references the option bytes
and sets specified functions. When using the product, be sure to set the following functions by using the option bytes.
Therefore, set values that are the same as those of 0080H to 0084H to 1080H to 1084H in advance.
(1) 0080H/1080H
(2) 0081H/1081H

The flash memory at 0080H to 0084H of the 78K0/Kx2-L microcontrollers is an option byte area. When power is
When the boot swap operation is used during self-programming, 0080H to 0084H are switched to 1080H to 1084H.
Internal low-speed oscillator operation
Watchdog timer interval time setting
Watchdog timer counter operation
Watchdog timer window open period setting
Caution Set a value that is the same as that of 0080H to 1080H because 0080H and 1080H are

Caution LVISTART can only be written by using a dedicated flash memory programmer. It cannot be
Can be stopped by software
Cannot be stopped
Enabled counter operation
Disabled counter operation
During LVI default start function enabled (LVISTART = 1)
The device is in the reset state after reset release or upon power application and until the supply voltage
reaches 1.91 V (TYP.). It is released from the reset state when the voltage exceeds 1.91 V (TYP.).
If the supply voltage rises to 1.8 V after reset release or power application at a rate slower than 0.5 V/ms
(MIN.), LVI default start function operation is recommended.
During LVI default start function stopped (LVISTART = 0)
The device is in the reset state after reset release or upon power application and until the supply voltage
reaches 1.61 V (TYP.). It is released from the reset state when the voltage exceeds 1.61 V (TYP.).
switched during the boot swap operation.
set or change during self-programming or boot swap operation during self-programming.
However, because 0080H and 1080H are switched during the boot swap operation, set a
value that is the same as that of 0080H to 1080H.
