Description
49
VDDC
P
1.8V digital core power input from VDDCO (Pin 56).
50
P1FFC
Ipu/O
PU = always enable (force) port 1 flow control feature
PD = port 1 flow control feature enable is determined by auto negotiation result.
51
P3SPD
Ipd/O
PU = force port 3 to 10BT
PD = force port 3 to 100BT (default)
52
NC
Unused pin. No external connection.
53
NC
Unused pin. No external connection.
54
VDDIO
P
3.3V, 2.5V or 1.8V digital VDD input power supply for IO with well decoupling
capacitors.
55
GND
Digital ground
56
VDDCO
P
1.8V core power voltage output (internal 1.8V LDO regulator output), this 1.8V
output pin provides power to both VDDA_1.8 and VDDC input pins.
Note: Internally 1.8V LDO regulator input comes from VDDIO. Do not connect an
external power supply to VDDCO pin. The ferrite bead is requested between
analog and digital 1.8V core power.
57
NC
Unused pin. No external connection.
58
P1LED1
Ipu/O
Port 1 LED Indicators: Default: Speed (refer to Register 195 bit[5:4])
Strap option: Port 3 flow control selection(P3FFC)
PU = always enable (force) port 3 flow control feature (default)
PD = disable
59
P1LED0
Ipd/O
Port 1 LED Indicators: Default: Link/Act. (refer to Register 195 bit[5:4])
Strap option: Port 3 duplex mode selection(P3DPX)
PU = port 3 to half duplex mode
PD = port 3 to full duplex mode (default)
Note: P1LED0 has weaker internal pull-down, recommend an external pull-down
by a 0.5K
Ω resistor.
