JTAG TRST.TTLIA8TRST
TXON of the Ethernet PHY.AnalogOL8TXON
TXOP of the Ethernet PHY.AnalogOM8TXOP
UART module 0 receive. When in IrDA mode, this signal has
IrDA modulation.
TTLIL3U0Rx
UART module 0 transmit. When in IrDA mode, this signal has
IrDA modulation.
TTLOM3U0Tx
UART module 1 receive. When in IrDA mode, this signal has
IrDA modulation.
TTLIH2U1Rx
UART module 1 transmit. When in IrDA mode, this signal has
IrDA modulation.
TTLOH1U1Tx
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.
Power-L12VBAT
VCC of the Ethernet PHY.Power-C10
D10
D11
VCCPHY
Positive supply for most of the logic function, including the
processor core and most peripherals.
Power-C3
D3
F3
G3
VDD25
Positive supply for I/O and some logic.Power-E10
G10

G12
H10
K7
K8
K9
VDD33
The positive supply for the analog circuits (ADC, Analog
Comparators, etc.). These are separated from VDD to
minimize the electrical noise contained on VDD from affecting
the analog functions. VDDA pins must be supplied with a
voltage that meets the specification in “Recommended DC
Operating Conditions” on page 748, regardless of system
implementation.
Power-C6
C7
VDDA
An external input that brings the processor out of Hibernate
mode when asserted.
TTLIM10WAKE
Hibernation module oscillator crystal input or an external clock
reference input. Note that this is either a crystal or a
32.768-kHz oscillator for the Hibernation module RTC.
AnalogIK11XOSC0
Hibernation module oscillator crystal output. Leave
unconnected when using a single-ended clock source.
AnalogOK12XOSC1
Ethernet PHY XTALN 25-MHz oscillator crystal output.
Connect this pin to ground when using a single-ended 25-MHz
clock input connected to the XTALPPHY pin.
TTLOJ1XTALNPHY
Ethernet PHY XTALP 25-MHz oscillator crystal input or
external clock reference input.
TTLIJ2XTALPPHY
a. The TTL designation indicates the pin has TTL-compatible voltage levels.
