11.15 RH850 type 1 (2-wire UART or CSI communications)
Notes: 1. These pins do not need to be short-circuited unless the FP6 is used with the E1, E20, or E2.
2. In case of using the alternate-function pin with a pull-up resistor, connect the pin to IO1 of the target connector.
In serial programming mode, the output on the IO1 pin is at the low level.
3. These pins do not need to be short-circuited when using 2-wire UART.
