11.Examples of Connections with Microcontrollers
The following shows examples of interface circuits. Refer to the recommended design for the connection of
pins for the MCU. The pin names might differ depending on the target device. For details about the actual pin
names, refer to the user’s manual of each target device.
11.1 78K and V850 (UART communications)
Notes: 1. These pins do not need to be short-circuited unless the FP6 is used with the E1 or E20.
2. In case of using the alternate-function pin with a pull-up resistor, connect the pin to FLMD1 of the target
connector. In flash memory programming mode, the output on the FLMD1 pin is at the low level.

Memory Microcontroller)
