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 (refer to Table 14-
10). In this case, operation stop mode or UART2 transmission must be selected for channel 0 of unit 1.
3. This pin can be set as a port function pin.
4. This is 0 or 1, depending on the communication operation. For details, refer to 14.3 (12) Serial output register
m (SOm).
5. When using UART2 transmission and reception in a pair, set channel 1 of unit 1 to UART2 reception (refer to
Table 14-10).
6. Set the CKO10 bit to 1 before a start condition is generated. Clear the SO10 bit from 1 to 0 when the start
condition is generated.
7. Set the CKO10 bit to 1 before a stop condition is generated. Clear the SO10 bit from 0 to 1 when the stop
condition is generated.
