The MAC scan chain for scan path testing can be input through MSCANI and output
through MSCANO. The scan chain, which is clocked on the rising edge of BYTCLK,
consists of the following signals (the reading order is from left to right):
MSCANI
TXDAT0
TXDAT1
TXDAT2
TXDAT3
TXDAT4
TXDAT5
TXDAT6
TXDAT7
TXDAT8
TXDAT9
RPATH0
RPATH1
RPATH2
RPATH3
RPATH4
RPATH5
RPATH6
RPATH7
RCCTL0
RCCTL1
RCCTL2
RCCTL3
RCCTL4
RABORT
TXRDY
TABORT
PARITY_ERR (Internal Signal)
TXCTL0
TXCTL1
TPATH0
TPATH1
TPATH2
TPATH3
TPATH4
TPATH5
TPATH6
TPATH7
PKTGEN8
(All PKTGEN are Internal Signals)
PKTGEN9
PKTGEN10
PKTGEN11
PKTGEN12
PKTGEN13
PKTGEN14
PKTGEN15
RCDAT0
RCDAT1
RCDAT2
RCDAT3
RCDAT4
RCDAT5
RCDAT6
RCDAT7
RCDAT8
RCDAT9
MSCANO
NOTE:
MSCANI and MSCANO are not latched pins but represent the input and output of the scan chain,
respectively. PKTGEN15–PKTGEN0 are internal latches in the scan chain.
