0x00 = No packets received.
0xFF = 256 packets received (maximum count). Bit
16_6.4 must be set to 1b in order for the register to be
valid.
0x00 = no CRC errors detected in the packets received.
0xFF = 256 CRC errors detected in the packets received
(maximum count). Bit 16_6.4 must be set to 1b in order
for the register to be valid.
Skew = bit value times 8 ns. The value is correct to
within ± 8 ns. The contents of 20_5.15:0 are valid only if
register 21_5.6 = 1b.
Skew = bit value times 8 ns. The value is correct to
within ± 8 ns.
Skew = bit value times 8 ns. The value is correct to
within ± 8 ns.
Skew = bit value times 8 ns. The value is correct to
within ± 8 ns.
The contents of 21_5.5:0 and 20_5.15:0 are valid
only if register 21_5.6 = 1b.
1b = Valid.
0b = Invalid.
1b = Channel C received on MDI[2]± Channel D
received on MDI[3]±.
0b = Channel D received on MDI[2]± Channel C
received on MDI[3]±.
1b = Channel A received on MDI[0]± Channel B
received on MDI[1]±.
