Type Definitions
Field ADDM7 reader - 7-bit Address Detection/4-bit Address Detection This bit is for selection between 4-bit address detection or 7-bit address detection. This bit can only be written when the LPUART is disabled (UEÂ =Â 0) Note: In 7-bit and 9-bit data modes, the address detection is done on 6-bit and 8-bit address (ADD[5:0]
and ADD[7:0]) respectively.
Field ADDM7 writer - 7-bit Address Detection/4-bit Address Detection This bit is for selection between 4-bit address detection or 7-bit address detection. This bit can only be written when the LPUART is disabled (UEÂ =Â 0) Note: In 7-bit and 9-bit data modes, the address detection is done on 6-bit and 8-bit address (ADD[5:0]
and ADD[7:0]) respectively.
Field ADD reader - Address of the LPUART node ADD[7:4]: These bits give the address of the LPUART node or a character code to be recognized. They are used to wake up the MCU with 7-bit address mark detection in multiprocessor communication during Mute mode or Stop mode. The MSB of the character sent by the transmitter should be equal to 1. They can also be used for character detection during normal reception, Mute mode inactive (for example, end of block detection in ModBus protocol). In this case, the whole received character (8-bit) is compared to the ADD[7:0]
value and CMF flag is set on match. These bits can only be written when reception is disabled (RE = 0) or the LPUART is disabled (UEÂ =Â 0) ADD[3:0]: These bits give the address of the LPUART node or a character code to be recognized. They are used for wakeup with address mark detection in multiprocessor communication during Mute mode or low-power mode. These bits can only be written when reception is disabled (RE = 0) or the LPUART is disabled (UEÂ =Â 0)
Field ADD writer - Address of the LPUART node ADD[7:4]: These bits give the address of the LPUART node or a character code to be recognized.

The MSB of the character sent by the transmitter should be equal to 1. They can also be used for character detection during normal reception, Mute mode inactive (for example, end of block detection in ModBus protocol). In this case, the whole received character (8-bit) is compared to the ADD[7:0]
value and CMF flag is set on match. These bits can only be written when reception is disabled (RE = 0) or the LPUART is disabled (UEÂ =Â 0) ADD[3:0]: These bits give the address of the LPUART node or a character code to be recognized. They are used for wakeup with address mark detection in multiprocessor communication during Mute mode or low-power mode. These bits can only be written when reception is disabled (RE = 0) or the LPUART is disabled (UEÂ =Â 0)
Field DATAINV reader - Binary data inversion This bit is set and cleared by software. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).
Field DATAINV writer - Binary data inversion This bit is set and cleared by software. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).
Field MSBFIRST reader - Most significant bit first This bit is set and cleared by software. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).
Field MSBFIRST writer - Most significant bit first This bit is set and cleared by software. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).
Field RXINV reader - RX pin active level inversion This bit is set and cleared by software. This enables the use of an external inverter on the RX line. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).

Field STOP reader - STOP bits These bits are used for programming the stop bits. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).
Field STOP writer - STOP bits These bits are used for programming the stop bits. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).
Field SWAP reader - Swap TX/RX pins This bit is set and cleared by software. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).
Field SWAP writer - Swap TX/RX pins This bit is set and cleared by software. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).
Field TXINV reader - TX pin active level inversion This bit is set and cleared by software. This enables the use of an external inverter on the TX line. This bitfield can only be written when the LPUART is disabled (UEÂ =Â 0).
