RCNCD2-0
000 : Received garbage data (noise) during the wait period after token sending (other than 000 to 101)
001 : Received a signal other than ACK during the wait period after packet sending
010 : Generated trailing 0 error after ACK receive during the wait period after packet sending
011 : Received a signal other than NAK/ACK during the wait period after F.B.E sending
100 : Generated trailing 0 error after ACK receive during the wait period after F.B.E sending
101 : Generated trailing 0 error after NAK receive during the wait period after F.B.E sending
11x : Undefined
001 to 101 do not generate reconfiguration since they are saved by NAK/ACK counter-deformation
function (nACKNAK = 0: default). The reconfiguration generation cause at nACKNAK = 0 is only 000.
CMIEI3-0 (bits 11 to 8)
These bits represent the CMI receive error correction code, which is the cause of CMIECC bit (bit 14) = 1
in the INTSTA register in three bits of CMIE2-0-0. In CMIEI3, it indicates which port is the generation port.
However, if HUB is turned off, the status is retained to 0. (0: Port 1 side, 1: Port 2 side)
Writing 1 to the CMIECC bit or software reset clears the setting in these bits.
CMIEI3
0: Port 1. 1: Port 2
CMIEI2-0
000 : Corrected error data 10 to 00 in State#11 (S11)
001 : Corrected error data 11 to 01 in State#11 (S11)
010 : Corrected error data 10 to 11 in State#00 (S00)
011 : Corrected error data 00 to 01 in State#00 (S00)
100 : Corrected error data 10 to 00 in State#01a (S01a)
101 : Corrected error data 11 to 01 in State#01a (S01a)
110 : Corrected error data 10 to 10 in State#01b (S01b)
111 : Corrected error data 00 to 01 in State#01b (S01b)
