Notes 1. The SE1 register is a read-only status register which is set using the SS1 and ST1 registers.<br />

2. Set the CKO11 bit to 1 before a start condition is generated. Clear the SO11 bit from 1 to 0 when the start condition is generated.<br />

3. This pin can be set as a port function pin or other alternate function pin.<br />

4. This is 0 or 1, depending on the communication operation. For details, refer to 12.3 (12) Serial output register m (SOm).<br />

5. Set the CKO11 bit to 1 before a stop condition is generated. Clear the SO11 bit from 0 to 1 when the stop condition is generated.<br />
