25.1
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
(3) 0084H/1084H
The flash memory at 0080H to 0084H of the 78K0/LF2 is an option byte area. When power is turned on or when
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
Cautions 1. Be sure to set 00H (disabling on-chip debug operation) to 0084H for products not equipped
Internal low-speed oscillator operation
Watchdog timer interval time setting
Watchdog timer counter operation
Watchdog timer window open period setting
Selecting POC mode
On-chip debug operation control
Functions of Option Bytes
Can be stopped by software
Cannot be stopped
Enabled counter operation
Disabled counter operation
During 2.7 V/1.59 V POC mode operation (POCMODE = 1)
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.).
If the supply voltage rises to 1.8 V after power application at a pace slower than 0.5 V/ms (MAX.), use of the
2.7 V/1.59 V POC mode is recommended.
During 1.59 V POC mode operation (POCMODE = 0)
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.
Disabling on-chip debug operation
Enabling on-chip debug operation and erasing data of the flash memory in case authentication of the on-
chip debug security ID fails
Enabling on-chip debug operation and not erasing data of the flash memory even in case authentication of
the on-chip debug security ID fails
function is used).
2. To use the on-chip debug function with products equipped with the on-chip debug function
with the on-chip debug function ( PD78F0372, 78F0373, 78F0374, 78F0375, 78F0376,
78F0382, 78F0383, 78F0384, 78F0385, and 78F0386). Also set 00H to 1084H because 0084H
and 1084H are switched at boot swapping.
( PD78F0376D and 78F0386D), set 02H or 03H to 0084H. Set a value that is the same as that
of 0084H to 1084H because 0084H and 1084H are switched at boot swapping.
