Note If "reception as 0 parity" is selected, the parity is not judged. Therefore, bit 2 (PE0) of asynchronous serial
interface reception error status register 0 (ASIS0) is not set and the error interrupt does not occur.
Cautions 1. Clear the TXE0 and RXE0 bits to 0 before rewriting the PS01, PS00, and CL0 bits.
2. Make sure that TXE0 = 0 when rewriting the SL0 bit. Reception is always performed with
"number of stop bits = 1", and therefore, is not affected by the set value of the SL0 bit.
