26.1 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 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.
Caution Be sure to set 00H to 0082H and 0083H (0082H/1082H and 0083H/1083H when the boot swap
Internal low-speed oscillator operation
• Can be stopped by software
• Cannot be stopped
Watchdog timer overflow 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
Selecting POC mode
• During 2.7 V/1.59 V POC mode operation (POCMODE = 1)
• During 1.59 V POC mode operation (POCMODE = 0)
Caution POCMODE can only be written by using a dedicated flash memory programmer. It cannot be set
The device is in the reset state upon power application and until the supply voltage reaches 2.7 V (TYP.). It is
released from the reset state when the voltage exceeds 2.7 V (TYP.). After that, POC is not detected at 2.7 V
but is detected at 1.59 V (TYP.).
With standard and (A) grade products, if the supply voltage rises to 1.8 V after power application at a rate slower
than 0.5 V/ms (MIN.), use of the 2.7 V/1.59 V POC mode is recommended.
The device is in the reset state upon power application and until the supply voltage reaches 1.59 V (TYP.). It is
released from the reset state when the voltage exceeds 1.59 V (TYP.). After that, POC is detected at 1.59 V
(TYP.), in the same manner as on power application.
function is used).
during the boot swap operation.
during self-programming or boot swap operation during self-programming. However, because
the value of 1081H is copied to 0081H during the boot swap operation, it is recommended to set
a value that is the same as that of 0081H to 1081H when the boot swap function is used.
