Configures mode of operation. Refer to Section 3.8.1.2.2, "Configuring the
Mode of Operation (CONFIG[3:2])," on page 31 for details.
Transmitter FIFO Depth
00 = 4 bytes
01 = 5 bytes
10 = 6 bytes
11 = 7 bytes
RESERVED
LED_MODE[1:0]
00 = Reserved
01 = LED mode 1
10 = LED mode 2
11 = LED mode 3
Refer to Section 3.9.1, "LEDs," on page 34 for additional information.
MACCLKDIS
0 = Normal mode, MACCLK pin is toggling at 125MHz or 25MHz
1 = Disable MACCLK pin from toggling, (driving it low)
MDI/MDI-X 0:1
Selects between MDI and MDI-X for channel 0 and channel 1 only if the Auto
MDIX Disable bit of the 10/100 Mode Control/Status Register is 1.
0 = MDI
1 = MDI-X
MDI/MDI-X 2:3
Selects between MDI and MDI-X for channel 2 and channel 3 only if the Auto
MDIX Disable bit of the 10/100 Mode Control/Status Register is 1.
0 = MDI
1 = MDI-X
CONDITIONAL PARALLEL DETECT
0 = Parallel detect. (Auto Negotiation Advertisement Register is ignored.)
1 = Conditional Parallel Detect only at the speed advertised in the Auto
Negotiation Advertisement Register.
10BASE-T half duplex (10BASE-T bit =1)
