8.5.4.13.8 DEBUG_COMH_RC
Address0x0784
Read OnlyBit 7Bit 6Bit 5Bit 4Bit 3Bit 2Bit 1Bit 0
NameRSVDRC_IERRRC_TXDISRC_SOFRC_BYTE _ERRRC_UNEXPRC_CRC
Reset00000000
RSVD =Reserved
RC_IERR =Detects initialization byte error in the received command frame. This may due to improper formatting of a byte such as a frame initialization byte is expected, but start-of-frame (SOF) bit is not set, or an invalid frame type is selected. Because bytes received on the COMH/COML are propagated up the stack, it is likely devices in the upper stack will also detect this error.
All bytes that follow are ignored until a SOF bit is set is received.
When a communication frame is ignored, the device will not attempt to detect any communication error in the ignored frame nor counting it as valid/discard in the frame counters.
0 = No error
1 = Error detected
RC_TXDIS =Valid when [DIR_SEL] = 1. Device detects the COMH TX is disabled but the device receives a command to read data (that is, to transmit data out). The command frame will be counted as a discard frame.
0 = No error
1 = Error detected
RC_SOF =Valid when [DIR_SEL] = 1. Detects a start-of-frame (SOF) error on COMH. The SOF bit is set only in the initialization frame but the SOF bit is set in the current frame that is not expected.
0 = No error
1 = Error detected
RC_BYTE_ERR =Valid when [DIR_SEL] = 1. Detected any byte error, other than the error in the initialization byte, in the received command frame. This error can trigger one or more error bit set in the DEBUG_COMMH_BIT register.
0 = No error
1 = Error detected
RC_UNEXP =If [DIR_SEL] = 0, but device receives command frame from COMH which is an invalid condition and device will set this error bit.
0 = No error
1 = Error detected
RC_CRC =Indicates a CRC error that resulted in one or more COMH command frames being discarded. Any other errors in the frame are not indicated as the frame was discarded.
0 = No error
1 = Error detected
