11.12 R8C
Note: These pins do not need to be short-circuited unless the FP6 is used with the E1, E20, or E8a.

11.13 RX (FINE communications)
Notes: 1. These pins do not need to be short-circuited unless the FP6 is used with the E1, E20, E2, or E2 Lite.
2. The UB pin controls entry to the user boot mode. Set up the UB pin to select the boot mode (SCI) or connect
the pin to IO2 of the target connector.
3. The value of the resistor should be 4.7 KΩ or more when the FP6 is used with the E1, E20, E2, or E2 Lite.
