IERR | Will be set any time COML vertical interface block has detected a physical layer fault on its initialization byte. This error can be caused one or more of faults as seen in physical layer at vertical interface register “COMM_COML_FAULT”. This bit is also set when a frame initialization byte is expected, but the SOF bit of the received byte is not set or an invalid frame type (one of the reserved commands) is selected. When this error occurs, communication is disregarded until an SOF byte is received. Any bytes received during this fault condition are forwarded, but are not processed by the device (i.e. CRC is not calculated and, therefore, no CRC error is indicated). Note: This bit can be set for both RC and RR.
0: No fault 1: Fault |
||||||
TXDIS | Indicates read command frame(s) were discarded because the TX is disabled on COML (Given DIR-SEL=0).
0: No fault 1: Fault |
||||||
SOF | Indicates a start of frame error on COML (frame start bit of '1' is received before the current frame is finished)
0: No fault 1: Fault |
||||||
BERR | Will be set any time COML vertical interface block has detected a physical layer fault on the second or later byte of a frame. This error can be caused one or more of faults as seen in physical layer at vertical interface register “COMM_COML_FAULT”. This is also can be set when a received data is interrupted by a transmit transit byte (came from UART to VIF, valid only on the base device).
0: No fault 1: Fault |
||||||
UNEXP | This bit is set if a command is received by COML when CONTROL1[DIR_SEL]=1. This also can be set if reverse command is received if DIR_SEL=0.
0: No fault 1: Fault |
||||||
CRC | Indicates a CRC error that resulted in one or more COML command frames being discarded. Any other errors in the frame are not indicated as the frame was discarded.
0: No fault 1: Fault |
