MRX_FRAM
Default: 0
Framing error indicates that the acknowledg-
ment frame contains a non-integer multiple of
eight bits and that there was an FCS error. If
there was no FCS error on the acknowledg-
ment frame, then MRX_FRAM will not be set
even if there was a non-integer multiples of
eight bits in the frame. MRX_FRAM is valid
while
MTX_MRX_FRAM is cleared by H_RESET.

MRX_FCS
Default: 0
Frame Check Sequence error indicates that
the receiver has detected an FCS (CRC) error
on the acknowledgment frame. MRX_FCS is
valid while MRX_ENABLE is set to 0.
MRX_FCS is cleared by H_RESET.
MRX_ERR
Default: 0
Receive Error is the OR of the MRX_FRAM
and MRX_FCS error. MRX_ERR is valid while
MRX_ENABLE is set to 0. MRX_ERR is
cleared by H_RESET.
