RX_DATA0_FRAME
_ERROR
R
W
0
Frame response, first data field frame error. HW sets
this field to '1' when the received STOP bits of the first
response data field have an unexpected value (only
after a RX_HEADER command), and this data byte is
0x00. HW clears this field to '0' at the falling edge of
SYNC start bit (after
INTR.RX_HEADER_BREAK_WAKEUP_DONE). This
field is used together with
INTR.RX_RESPONSE_FRAME_ERROR to
distinguish 'no response', 'error response' and 'correct
response' scenarios.
Note: The ongoing message transfer is NOT aborted.
8
TX_BUSY
R
W
0
Transmitter busy.
- Set to '1' on the start of the following commands:
TX_HEADER, TX_RESPONSE, TX_WAKEUP.
- Set to '0' on successful completion of previous
commands or when an error is detected.
In 'TX_HEADER, RX_RESPONSE' case, set to '0' at
the start bit falling edge in the first response data byte,
after header transmission
9
RX_BUSY
R
W
0
Receiver busy.
- Set to '1' on the start of the following commands:
RX_HEADER, RX_RESPONSE.
in RX_HEADER case, set at Break filed rising edge.
in RX_RESPONSE case, set at the start bit falling
edge in the first response data byte.
- Set to '0' on successful completion of previous
commands or when an error is detected.
12
TX_DONE
R
W
0
Transmitter done:
- Set to '0' on the start of a new command.
- Set to '1' on successful completion of the following
command sequences (if CTL.AUTO_EN is '1', this
includes the 4-bit period external transceiver disable
post-amble):
- TX_HEADER.
- TX_HEADER, TX_RESPONSE.
- RX_HEADER, TX_RESPONSE.
- TX_WAKEUP.
13
RX_DONE
R
W
0
Receiver done:
- Set to '0' on the start of a new command.
- Set to '1' on successful completion of the following
command sequences (if CTL.AUTO_EN is '1', this
includes the 4-bit period external transceiver disable
post-amble):
- RX_HEADER, RX_RESPONSE.
- TX_HEADER, RX_RESPONSE.
