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

interface reception error status register 6 (ASIS6) is not set and the error interrupt does not occur.
2. To start the reception, set POWER6 to 1 and then set RXE6 to 1. To stop the reception, clear
3. Set POWER6 to 1 and then set RXE6 to 1 while a high level is input to the R

5. Set transmit data to TXB6 at least one base clock (f
6. Clear the TXE6 and RXE6 bits to 0 before rewriting the PS61, PS60, and CL6 bits.
7. Fix the PS61 and PS60 bits to 0 when used in LIN communication operation.
8. Clear TXE6 to 0 before rewriting the SL6 bit.
9. Make sure that RXE6 = 0 when rewriting the ISRM6 bit.

POWER6 is set to 1 and RXE6 is set to 1 while a low level is input, reception is started.
transmission or reception again, set TXE6 or RXE6 to 1 at least two clocks of the base clock
after TXE6 or RXE6 has been cleared to 0. If TXE6 or RXE6 is set within two clocks of the
base clock, the transmission circuit or reception circuit may not be initialized.
