LPUART Status Register
| MA2F | Match 2 Flag 0 (0): Received data is not equal to MA2 1 (1): Received data is equal to MA2 |
| MA1F | Match 1 Flag 0 (0): Received data is not equal to MA1 1 (1): Received data is equal to MA1 |
| PF | Parity Error Flag 0 (0): No parity error. 1 (1): Parity error. |
| FE | Framing Error Flag 0 (0): No framing error detected. This does not guarantee the framing is correct. 1 (1): Framing error. |
| NF | Noise Flag 0 (0): No noise detected. 1 (1): Noise detected in the received character in LPUART_DATA. |
| OR | Receiver Overrun Flag 0 (0): No overrun. 1 (1): Receive overrun (new LPUART data lost). |
| IDLE | Idle Line Flag 0 (0): No idle line detected. 1 (1): Idle line was detected. |
| RDRF | Receive Data Register Full Flag 0 (0): Receive data buffer empty. 1 (1): Receive data buffer full. |
| TC | Transmission Complete Flag 0 (0): Transmitter active (sending data, a preamble, or a break). 1 (1): Transmitter idle (transmission activity complete). |
| TDRE | Transmit Data Register Empty Flag 0 (0): Transmit data buffer full. 1 (1): Transmit data buffer empty. |
| RAF | Receiver Active Flag 0 (0): LPUART receiver idle waiting for a start bit. 1 (1): LPUART receiver active (LPUART_RX input not idle). |
| LBKDE | LIN Break Detection Enable 0 (0): Break character is detected at length 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 or M10 = 1, SNBS = 0) or 13 (if M10 = 1, SNBS = 1). 1 (1): Break character is detected at length of 11 bit times (if M = 0, SBNS = 0) or 12 (if M = 1, SBNS = 0 or M = 0, SBNS = 1) or 14 (if M = 1, SBNS = 1 or M10 = 1, SNBS = 0) or 15 (if M10 = 1, SNBS = 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 or M10 = 1, SNBS = 0) or 13 (if M10 = 1, SNBS = 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 or M10 = 1, SNBS = 0) or 16 (if M10 = 1, SNBS = 1). |
| RWUID | Receive Wake Up Idle Detect 0 (0): During receive standby state (RWU = 1), the IDLE bit does not get set upon detection of an idle character. During address match wakeup, the IDLE bit does not get set when an address does not match. 1 (1): During receive standby state (RWU = 1), the IDLE bit gets set upon detection of an idle character. During address match wakeup, the IDLE bit does get set when an address does not match. |
| RXINV | Receive Data Inversion 0 (0): Receive data not inverted. 1 (1): Receive data inverted. |
| MSBF | MSB First 0 (0): LSB (bit0) is the first bit that is transmitted following the start bit. Further, the first bit received after the start bit is identified as bit0. 1 (1): MSB (bit9, bit8, bit7 or bit6) is the first bit that is transmitted following the start bit depending on the setting of CTRL[M], CTRL[PE] and BAUD[M10]. Further, the first bit received after the start bit is identified as bit9, bit8, bit7 or bit6 depending on the setting of CTRL[M] and CTRL[PE]. |
| RXEDGIF | LPUART_RX 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. |
