In the flash memory programming mode, connect this pin directly to the dedicated flash memory programmer or
When on-chip debugging is enabled in the normal operation mode, pull this pin up by connecting it to EV
Remark The SAU and IIC0 pins are not used for communication between the 78K0R/KE3 and dedicated flash
Signal conflict will occur if the reset signal of the dedicated flash memory programmer is connected to the RESET
The flash memory will not be correctly programmed if the reset signal is input from the user system while the flash
It is recommended to leave this pin open when using the self programming function. To pull it down externally,
use a resistor of 100 kΩ to 200 kΩ.
In the self programming mode, the setting is switched to pull up in the self programming library.

In the flash memory programming mode, a signal output by another device
will conflict with the signal output by the dedicated flash memory
programmer. Therefore, isolate the signal of another device.
