Notes 1. The SE1 register is a read-only status register which is set using the SS1 and ST1 registers.
2. This pin can be set as a port function pin.
3. This is 0 or 1, depending on the communication operation. For details, refer to 14.3 (12) Serial output register
m (SOm).
4. When using UART3 transmission and reception in a pair, set channel 3 of unit 1 to UART3 reception (refer to
Table 14-12).

2. This pin can be set as a port function pin.
3. When using UART3 transmission and reception in a pair, set channel 2 of unit 1 to UART3 transmission (refer to
Table 14-11).
4. The SMR12 register of channel 2 of unit 1 must also be set during UART3 reception. For details, refer to 14.5.2
