Universal asynchronous receiver transmitter (UART) RM0016

22.7.6 Control register 2 (UART_CR2)
Address offset: 0x05
Reset value: 0x00
Bit 2 PCEN: Parity control enable.
–UART Mode
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 parity
is checked on the received data. This bit is set and cleared by software. Once it is set, PCEN is
active after the current byte (in reception and in transmission).
0: Parity control disabled
1: Parity control enabled
– LIN slave mode
This bit enables the LIN identifier parity check while the UART is in LIN slave mode.
0: Identifier parity check disabled
1: Identifier parity check enabled
Bit 1 PS: Parity selection.
This bit selects the odd or even parity when the parity generation/detection is enabled (PCEN bit set)
in UART mode. It is set and cleared by software. The parity will be selected after the current byte.
0: Even parity
1: Odd parity
Bit 0 PIEN: Parity interrupt enable.
This bit is set and cleared by software.
0: Parity interrupt disabled
1: Parity interrupt is generated whenever PE=1 in the UART_SR register

rw rw rw rw rw rw rw rw
Bit 7 TIEN: Transmitter interrupt enable
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An UART interrupt is generated whenever TXE=1 in the UART_SR register
Bit 6 TCIEN: Transmission complete interrupt enable
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An UART interrupt is generated whenever TC=1 in the UART_SR register
Bit 5 RIEN: Receiver interrupt enable
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An UART interrupt is generated whenever OR=1 or RXNE=1 in the UART_SR register
Bit 4 ILIEN: IDLE Line interrupt enable
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An UART interrupt is generated whenever IDLE=1 in the UART_SR register
