Description

Power supply

VDD

Input

Power supply pin. Connect this pin to the system power supply.

VSS

Input

Ground pin. Connect this pin to the system power supply (0 V).

VCCQ33

Input

Power supply pin for I/O pins

PLLVDD0, PLLVDD1

Input

Power supply pins for the on-chip PLL oscillator

PLLVSS0, PLLVSS1

Input

Ground pins for the on-chip PLL oscillator. Connect these pins to

the system power supply (0 V).

Clock

XTAL

Output

Connected to a crystal resonator. An external clock signal may

also be input to the EXTAL pin.

EXTAL

Input

CKIO

Output

Outputs the external bus clock for external devices.

AUDIO_CLK

Input

Inputs the external clock for audio.

CLKOUT25M0,

CLKOUT25M1,

CLKOUT25M2

Output

Output the external clock for Ethernet PHY.

Operating mode control

MD0 to MD2

Input

Input the operating mode select signal.

System control

RES#

Input

Reset signal input pin. This LSI enters the reset state when this

signal goes low.

BSCANP

Input

Inputs the boundary scan enable signal. Boundary scan is enabled

when this pin goes high. When not used, it should be driven low.

OSCTH

Input

Inputs the clock input mode select signal. When an external clock

is input, this pin should be driven high. When a crystal resonator is

connected, it should be driven low.

ERROROUT#

Output

Outputs the error signal from the error control module (ECM).

RSTOUT#

Output

Outputs the reset signal externally.

Debugging interface

TRST#

Input

Test reset pin for on-chip emulator

TMS

I/O

Test mode select pin for on-chip emulator

TDI

Input

Test data input pin for on-chip emulator

TDO

Output

Test data output pin for on-chip emulator

TCK

Input

Test clock pin for on-chip emulator

TRACECLK

Output

Outputs the clock for synchronization with the trace data.

TRACECTL

Output

Outputs the enable signal for trace control.

TRACEDATA0 to

TRACEDATA7

Output

Output the trace data.
