Description

UART Status Register 2

Fields

RAF

Receiver Active Flag

0 (0): UART receiver idle waiting for a start bit.

1 (1): UART receiver active (RxD input not idle).

LBKDE

LIN Break Detection Enable

0 (0): Break detection is disabled.

1 (1): Break detection is enabled (Break character is detected at length 11 bit times (if C1[M] = 0, BDH[SBNS] = 0) or 12 (if C1[M] = 1, BDH[SBNS] = 0 or C1[M] = 0, BDH[SBNS] = 1) or 13 (if C1[M] = 1, BDH[SBNS] = 1)).

BRK13

Break Character Generation Length

0 (0): Break character is transmitted with length of 10 bit times (if M = 0, SBNS = 0) or 11 (if M = 1, SBNS = 0 or M = 0, SBNS = 1) or 12 (if M = 1, SBNS = 1).

1 (1): Break character is transmitted with length of 13 bit times (if M = 0, SBNS = 0) or 14 (if M = 1, SBNS = 0 or M = 0, SBNS = 1) or 15 (if M = 1, SBNS = 1).

RWUID

Receive Wake Up Idle Detect

0 (0): During receive standby state (RWU = 1), S1[IDLE] does not get set upon detection of an idle character.

1 (1): During receive standby state (RWU = 1), S1[IDLE] gets set upon detection of an idle character.

RXINV

Receive Data Inversion

0 (0): Receive data not inverted.

1 (1): Receive data inverted.

RXEDGIF

RxD Pin Active Edge Interrupt Flag

0 (0): No active edge on the receive pin has occurred.

1 (1): An active edge on the receive pin has occurred.

LBKDIF

LIN Break Detect Interrupt Flag

0 (0): No LIN break character has been detected.

1 (1): LIN break character has been detected.
