OBSOLETE: TI has discontinued production of this device.
Table 18-2. Signals by Pin Number (continued)
Pin Number
Pin Name
Pin Type Buffer Type^a Description
VDDC
38
-
Power Positive supply for most of the logic function, including the
processor core and most peripherals. The voltage on this pin is
1.3 V and is supplied by the on-chip LDO. The VDDC pins should
only be connected to the LDO pin and an external capacitor as
specified in Table 20-6 on page 780 .
39
GND
-
Power Ground reference for logic and I/O pins.
40
RXIP
I
Analog RXIP of the Ethernet PHY.
41
ERBIAS
O
Analog 12.4-kΩ resistor (1% precision) used internally for Ethernet PHY.
42
GND
-
Power Ground reference for logic and I/O pins.
43
TXOP
O
TTL
TXOP of the Ethernet PHY.
44
VDD
-
Power Positive supply for I/O and some logic.
45
GND
-
Power Ground reference for logic and I/O pins.
46
TXON
O
TTL
TXON of the Ethernet PHY.
PF0
I/O
TTL
GPIO port F bit 0.
47
U1DSR
I
TTL
UART module 1 Data Set Ready modem output control line.
48
OSC0
I
Analog Main oscillator crystal input or an external clock reference input.
49
OSC1
O
Analog Main oscillator crystal output. Leave unconnected when using a
single-ended clock source.
50
WAKE
I
TTL
An external input that brings the processor out of Hibernate mode
when asserted.
51
HIB
O
OD
An output that indicates the processor is in Hibernate mode.
XOSC0
52
I
Analog Hibernation module oscillator crystal input or an external clock
reference input. Note that this is either a 4.194304-MHz crystal or
a 32.768-kHz oscillator for the Hibernation module RTC. See the
CLKSEL bit in the HIBCTL register.
53
XOSC1
O
Analog Hibernation module oscillator crystal output. Leave unconnected
when using a single-ended clock source.
54
GND
-
Power Ground reference for logic and I/O pins.
VBAT
55
-
Power Power source for the Hibernation module. It is normally connected
to the positive terminal of a battery and serves as the battery
backup/Hibernation module power-source supply.
56
VDD
-
Power Positive supply for I/O and some logic.
57
GND
-
Power Ground reference for logic and I/O pins.
58
MDIO
I/O
OD
MDIO of the Ethernet PHY.
PF3
I/O
TTL
GPIO port F bit 3.
59

TTL
Ethernet LED 0.
SSI1Fss
I/O
TTL
SSI module 1 frame signal
PF2
I/O
TTL
GPIO port F bit 2.
60
LED1
O
TTL
Ethernet LED 1.
SSI1Clk
I/O
TTL
SSI module 1 clock
PF1
I/O
TTL
GPIO port F bit 1.
61
CCP3
