Note If “reception as 0 parity” is selected, the parity is not judged. Therefore, bit 2 (PE6) of asynchronous serial
Cautions 1. At startup, set POWER6 to 1 and then set TXE6 to 1. To stop the operation, clear TXE6 to 0,

interface reception error status register 6 (ASIS6) is not set and the error interrupt does not occur.
2. At startup, set POWER6 to 1 and then set RXE6 to 1. To stop the operation, clear RXE6 to 0,
3. Set POWER6 to 1 and then set RXE6 to 1 while a high level is input to the RxD6 pin. If
4. Clear the TXE6 and RXE6 bits to 0 before rewriting the PS61, PS60, and CL6 bits.
5. Fix the PS61 and PS60 bits to 0 when mounting the device on LIN.
6. Make sure that TXE6 = 0 when rewriting the SL6 bit. Reception is always performed with “the
