Description
0
TX_HEADER
RW1S
RW
0
SW sets this field to '1' to transmit a header. HW sets
this field to '0' on successful completion of ANY of the
following legal command sequences (also set to '0'
when an error is detected):
- TX_HEADER
- TX_HEADER, TX_RESPONSE.
- TX_HEADER, RX_RESPONSE.
- RX_HEADER, TX_RESPONSE.
- RX_HEADER, RX_RESPONSE.
- TX_WAKEUP.
The header is transmitted when the PID field STOP
bits are transmitted (INTR.TX_HEADER_DONE).
HW sets this field to '1', when the 'tr_cmd_tx_header'
input trigger is activated. This allows for time triggered
LIN message transfer. HW driven time triggered
transfer eliminates the jitter that is typically associated
with SW driven transfer.
In UART mode, a single data field (DATA0.DATA1) is
transmitted.
1
TX_RESPONSE
RW1S
RW1C
0
SW sets this field to '1' to transmit a response. HW
sets this field to '0' on successful completion of ANY of
the legal command sequences (also set to '0' when an
error is detected).
The response is transmitted when the checksum field
STOP bits are transmitted
(INTR.TX_RESPONSE_DONE).
2
TX_WAKEUP
RW1S
RW1C
0
SW sets this field to '1' to transmit a wakeup signal.
HW sets this field to '0' on successful completion of
ANY of the legal command sequences (also set to '0'
when an error is detected).
The command generates
CTL.BREAK_WAKEUP_LENGTH bit periods in the
dominant state (low/'0') and transitions to the recessive
state (high/'1') (INTR.TX_WAKEUP_DONE).
