Channel Interface with PCS-PMA
set to 8/10 bits
Two 8-bit unencoded Data (
rx_dataout )
rx_dataoutfull[7:0] - rx_dataout (LSByte) and
rx_dataoutfull[23:16] - rx_dataout (MSByte)
The following signals are used in 16-bit 8B/10B modes:
Two Control Bits
rx_dataoutfull[8] - rx_ctrldetect (LSB) and
rx_dataoutfull[24] - rx_ctrldetect (MSB)
Two Receiver Error Detect Bits
rx_dataoutfull[9] - rx_errdetect (LSB) and
rx_dataoutfull[25] - rx_errdetect (MSB)
Two Receiver Sync Status Bits
rx_dataoutfull [10] - rx_syncstatus (LSB) and
rx_dataoutfull[26] - rx_syncstatus (MSB)
Two Receiver Disparity Error Bits
rx_dataoutfull [11] - rx_disperr (LSB) and
rx_dataoutfull[27] - rx_disperr (MSB)
Two Receiver Pattern Detect Bits
rx_dataoutfull[12] - rx_patterndetect (LSB) and
rx_dataoutfull[28] - rx_patterndetect (MSB)
rx_dataoutfull[13] and rx_dataoutfull[29] : Rate Match FIFO deletion status
indicator (
rx_rmfifodatadeleted ) in non-PCI Express (PIPE) functional modes
rx_dataoutfull[14] and rx_dataoutfull[30] : Rate Match FIFO insertion status
indicator (
rx_rmfifodatainserted ) in non-PCI Express (PIPE) functional modes
Two 2-bit PCI Express (PIPE) Functional Mode Status Bits
rx_dataoutfull[14:13] - rx_pipestatus (LSB) and rx_dataoutfull[30:29] -
rx_pipestatus (MSB)
rx_dataoutfull[15] and rx_dataoutfull[31] : 8B/10B running disparity
indicator (
rx_runningdisp )
