In the flash memory programming mode, connect this pin directly to the dedicated flash memory programmer or pull it
When on-chip debugging is enabled in the normal operation mode, pull this pin up by connecting it to V
Remark The SAU and IICA pins are not used for communication between the 78K0R/Lx3 microcontrollers and
Signal conflict will occur if the reset signal of the dedicated flash memory programmer is connected to the RESET pin
The flash memory will not be correctly programmed if the reset signal is input from the user system while the flash
When the flash memory programming mode is set, all the pins not used for flash memory programming enter the same
Connect the REGC pin to GND via a capacitor (0.47 to 1
Also, use a capacitor with good characteristics, since it is used to stabilize internal voltage.
Connect X1 and X2 in the same status as in the normal operation mode.
