Notes 1. The SE0 register is a read-only status register which is set using the SS0 and ST0 registers.
2. When channel 3 of unit 0 is set to UART1 reception, this pin becomes an RxD1 function pin. In this case, set
channel 2 of unit 0 to operation stop mode or UART1 transmission (refer to Table 14-7).
When channel 2 of unit 0 is set to CSI10 or IIC10, this pin cannot be used as an RxD1 function pin. In this case,
set channel 3 of unit 0 to operation stop mode.
3. This pin can be set as a port function pin.
4. When using UART1 transmission and reception in a pair, set channel 2 of unit 0 to UART1 transmission (refer to
Table 14-7).
5. The SMR02 register of channel 2 of unit 0 must also be set during UART1 reception. For details, refer to 14.5.2
(1) Register setting.
