11.16 RH850 type 2 (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. These pins do not need to be short-circuited when using 2-wire UART.

RH850/E1x)
11.17 Renesas Synergy (UART communications)
Notes: 1. The value of each resistor should be in the range from 4.7 KΩ to 10 KΩ.
2. Some target devices do not require an external clock circuit. To check if the clock circuit is necessary, see the
user’s manual of the target device.
