Notes 1. The SE1 register is a read-only status register which is set using the SS1 and ST1 registers.
2. When channel 1 of unit 1 is set to UART2 reception, this pin becomes an RxD2 function pin. In this case, set
channel 0 of unit 1 to operation stop mode or UART2 transmission (refer to Table 14-9).
When channel 0 of unit 1 is set to CSI20 or IIC20, this pin cannot be used as an RxD2 function pin. In this case,
set channel 1 of unit 1 to operation stop mode.
3. This pin can be set as a port function pin.
4. When using UART2 transmission and reception in a pair, set channel 0 of unit 1 to UART2 transmission (refer to
Table 14-9).
5. The SMR10 register of channel 0 of unit 1 must also be set during UART2 reception. For details, refer to 14.5.2
(1) Register setting.
