24.1 Functions of Option Bytes
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 turned
When the boot swap operation is used during self-programming, 0080H to 0084H are switched to 1080H to 1084H.
Internal low-speed oscillator operation
• Can be stopped by software
• Cannot be stopped
Watchdog timer interval time setting
Watchdog timer counter operation
• Enabled counter operation
• Disabled 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 switched
LVI default start operation control
• During LVI default start function enabled (LVISTART = 1)
• During LVI default start function stopped (LVISTART = 0)
Caution LVISTART can only be written by using a dedicated flash memory programmer. It cannot be set
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.
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.).
during the boot swap operation.
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.
