Bit 5 – SMD_ERR Illegal SMD Received (Clear on read)
| Value | Description |
|---|---|
| 0 | No illegal SMD received since the last read of GMAC_MMSL_ISR. |
| 1 | Illegal SMD received (different from Express, Verify, Response, Start Preemptible or Continuation Preemptible) since the last read of GMAC_MMSL_ISR |
Bit 4 – FR_COUNT_ERR Illegal SMD Received (Clear on read)
| Value | Description |
|---|---|
| 0 | No frame count error detected since the last read of GMAC_MMSL_ISR. |
| 1 | The SMD-C received since the last read of GMAC_MMSL_ISR indicates a different frame count than expected (i.e. the fragment belongs to another frame and not to the Start packet already received before this) or that a fragment error hoccurred, meaning that the field following the SMD-C received was encoding a different fragment count than it was supposed to be. |
Bit 3 – SMDC_ERR SMD-C Received When Waiting an SMD-S (Clear on read)
| Value | Description |
|---|---|
| 0 | No error since the last read of GMAC_MMSL_SR. |
| 1 | An SMD-C has been received when an SMD-S was expected since the last read of GMAC_MMSL_SR. |
Bit 2 – SMDS_ERR SMD-S Received When Waiting an SMD-C (Clear on read)
| Value | Description |
|---|---|
| 0 | No error since the last read of GMAC_MMSL_SR. |
| 1 | An SMD-S has been received when an SMD-C was expected since the last read of GMAC_MMSL_SR. |
Bit 1 – RCV_V_ERR Incorrect Verification Mpacket Received (Clear on read)
| Value | Description |
|---|---|
| 0 | No error since the last read of GMAC_MMSL_SR. |
| 1 | An incorrect verification mPacket has been received since the last read of GMAC_MMSL_SR. |
Bit 0 – RCV_R_ERR Incorrect Response Mpacket Received (Clear on read)
| Value | Description |
|---|---|
| 0 | No error since the last read of GMAC_MMSL_SR. |
| 1 | An incorrect response mPacket has been received since the last read of GMAC_MMSL_SR. |
