7.5.1 CXPI_ERROR_CTL
Description:
Error control
Address:
0x40510000
Offset:
0x0
Retention:
Retained
IsDeepSleep:
No
Comment:
This register supports error functionality: it enables HW injected channel transmitter errors.
The receiver should detect these errors and report these errors through activation of
corresponding interrupt causes.
Default:
0x0

CH_IDX
RW

0
Specifies the channel index of the channel to which
HW injected channel transmitter errors applies.
18
TX_CRC_ERROR
RW
R
0
The crc field is inverted.
At the receiver, this should result in
INTR.RX_CRC_ERROR activation.
19
TX_PID_PARITY
_ERROR
RW
R
0
In cxpi mode, the PID parity bit P[1] is inverted from
!(ID[5] ^ ID[4] ^ ID[3] ^ ID[1]) to (ID[5] ^ ID[4] ^ ID[3] ^
ID[1]).
At the receiver, this should result in
INTR.RX_HEADER_PARITY_ERROR activation.
20
TX_DATA_LENGTH
_ERROR
RW
R
0
The transmitter continues to send logical '0' (during
IFS) after CRC field is transmitted.
At the receiver, this should result in
INTR.RX_DATA_LENGTH_ERROR activation.
At the transmitter, this should result in
INTR.TX_DATA_LENGTH_ERROR activation.
25
TX_DATA_STOP
_ERROR
RW
R
0
The data field STOP bits are inverted to '0'.
At the receiver, this should result in
INTR.RX_FRAME_ERROR activation.
At the transmitter, this should result in
INTR.TX_FRAME_ERROR activation.
