PERR = | Detect abnormality of the incoming communication frame and the
outgoing communication frame will be set with BERR. Any error bit
that is set in this register will also set the [PERR] bit.
However, abnormality that is not classified in the register can also
trigger the [PERR] bit (for example, detecting missing data
or wrong data order. 0 = No communication error detected, the forwarded communication frame does not have the BERR inserted 1 = Detected abnormality of the received communication frame. BERR is asserted to the forwarded communication. | |||||||
BERR_TAG = | Set when the received communication is tagged with BERR. 0 = Received communication frame has no BERR 1 = Received communication frame has BERR | |||||||
SYNC2 = | The Preamble half-bit and the [SYNC1:0] bits are detected. Device is using the timing information that is extracted from these bits but it is unable to detect valid data. 0 = No error 1 = Error detected | |||||||
SYNC1 = | Unable to detect the preamble half-bit or any of the [SYNC1:0] bits. It could be the bit is missing or the signal is too distorted to be detectable. 0 = No error 1 = Error detected | |||||||
BIT = | The device has detected a data bit. However, the detection samples are not enough to assure a strong 1 or 0. 0 = No error 1 = Error detected |
