Bit 10 PCE: Parity Control Enable. This bit selects the hardware parity control (generation and detection). When the parity control isenabled, the computed parity is inserted at the MSB position (9th bit if M=1; 8th bit if M=0) and parity is checked on the received data. This bit is set and cleared by software. Once it is set, PCE isactive after the current byte (in reception and in transmission).
