Description
13
RX_NOISE_DETECT
RW1C
RW1S
0
HW sets this field to '1', when isolated '0' or '1'
'in_rx_in' values are observed or when during sampling
the last three 'lin_rx_in' values do NOT all have the
same value. This mismatch is an indication of noise on
the LIN line.
Note: The ongoing frame transfer is NOT aborted.
Note: Used in UART mode.
14
TIMEOUT
RW1C
RW1S
0
HW sets this field to '1', when a frame, frame header or
frame response timeout is detected (per
CTL.FRAME_TIMEOUT_SEL).
Note: The ongoing frame transfer is NOT aborted.
16
TX_HEADER_BIT
_ERROR
RW1C
RW1S
0
HW sets this field to '1', when a transmitted 'lin_tx_out'
value does NOT match a received 'lin_rx_in' value
(during header transmission). This specific test allows
for delay through the external transceiver. This
mismatch is an indication of bus collisions on the LIN
line.
The match is performed for the Wakeup, Break, SYNC
and the PID fields (for the START bit, data Byte and
STOP bit).
Note: When CTL.BIT_ERROR_IGNORE is '0', the
ongoing message transfer is aborted
(INTR.TX_HEADER_DONE is NOT activated) and the
TX_HEADER, TX_RESPONSE and TX_WAKEUP
commands are set to '0'.
Note: Used in UART mode.
17
TX_RESPONSE_BIT
_ERROR
RW1C
RW1S
0
HW sets this field to '1', when a transmitted 'lin_tx_out'
value does NOT match a received 'lin_rx_in' value
(during response transmission).
The match is performed for the data fields and the
checksum field (for the START bit, data Byte and
STOP bit).
Note: When CTL.BIT_ERROR_IGNORE is '0', the
ongoing message transfer is aborted
(INTR.TX_RESPONSE_DONE is NOT activated) and
the TX_HEADER, TX_RESPONSE and TX_WAKEUP
commands are set to '0'.
24
RX_HEADER_FRAME
_ERROR
RW1C
RW1S
0
HW sets this field to '1', when the received START or
STOP bits have an unexpected value (during header
reception).
Note: The ongoing message transfer is aborted
(INTR.RX_HEADER_DONE is NOT activated) and the
TX_HEADER, TX_RESPONSE and TX_WAKEUP
commands are set to '0'.
Note: Used in UART mode.
