RM0440 Universal synchronous/asynchronous receiver transmitter (USART/UART)

1733

Bit 11 WAKE: Receiver wakeup method

This bit determines the USART wakeup method from Mute mode. It is set or cleared by

software.

0: Idle line

1: Address mark

This bitfield can only be written when the USART is disabled (UE=0).

Bit 10 PCE: Parity control enable

This bit selects the hardware parity control (generation and detection). When the parity

control is enabled, the computed parity is inserted at the MSB position (9th bit if M=1; 8th bit

if M=0) and the parity is checked on the received data. This bit is set and cleared by software.

Once it is set, PCE is active after the current byte (in reception and in transmission).

0: Parity control disabled

1: Parity control enabled

This bitfield can only be written when the USART is disabled (UE=0).

Bit 9 PS: Parity selection

This bit selects the odd or even parity when the parity generation/detection is enabled (PCE

bit set). It is set and cleared by software. The parity is selected after the current byte.

0: Even parity

1: Odd parity

This bitfield can only be written when the USART is disabled (UE=0).

Bit 8 PEIE: PE interrupt enable
