Description

LPUART control register 2

Fields

ADDM7

7-bit Address Detection/4-bit Address Detection

0 (B_0x0): 4-bit address detection

1 (B_0x1): 7-bit address detection (in 8-bit data mode)

STOP

STOP bits

0 (B_0x0): 1 stop bit

2 (B_0x2): 2 stop bits

SWAP

Swap TX/RX pins

0 (B_0x0): TX/RX pins are used as defined in standard pinout

1 (B_0x1): The TX and RX pins functions are swapped. This enables to work in the case of a cross-wired connection to another UART.

RXINV

RX pin active level inversion

0 (B_0x0): RX pin signal works using the standard logic levels (Vless thansub>DDless than/sub> =1/idle, Gnd=0/mark)

1 (B_0x1): RX pin signal values are inverted. ((Vless thansub>DDless than/sub> =0/mark, Gnd=1/idle).

TXINV

TX pin active level inversion

0 (B_0x0): TX pin signal works using the standard logic levels (Vless thansub>DDless than/sub> =1/idle, Gnd=0/mark)

1 (B_0x1): TX pin signal values are inverted. ((Vless thansub>DDless than/sub> =0/mark, Gnd=1/idle).

DATAINV

Binary data inversion

0 (B_0x0): Logical data from the data register are send/received in positive/direct logic. (1=H, 0=L)

1 (B_0x1): Logical data from the data register are send/received in negative/inverse logic. (1=L, 0=H). The parity bit is also inverted.

MSBFIRST

Most significant bit first

0 (B_0x0): data is transmitted/received with data bit 0 first, following the start bit.

1 (B_0x1): data is transmitted/received with the MSB (bit 7/8) first, following the start bit.

ADD

Address of the LPUART node
