Data Sheet

Ethernet Interface

EMCCD

Collision detection.

3.3V LVTTL

EMCCrS

Carrier sense.

3.3V LVTTL

EMCMDClk

Management data clock.

3.3V LVTTL

EMCMDIO

Transfer command and status information between MII

and PHY.

I/O

3.3V LVTTL

3.3V LVTTL

External Slave Peripheral Interface

PerAddr00:23

Peripheral address bus.

Note:PerAddr00 is the most significant bit (msb).

O3.3V LVTTL

PerBE0

External peripheral data bus byte enable.

3.3V LVTTL

PerBLast

Used by the peripheral controller to indicates the last

transfer of a memory access.

O3.3V LVTTL

PerCS0:2

External peripheral device select.

3.3V LVTTL

PerData0:7

Peripheral data bus.

Note:PerData0 is the most significant bit (msb).

I/O

3.3V LVTTL

PerOE

Used by peripheral controller or DMA controller

depending upon the type of transfer involved. When the

PPC440SP is the bus master, it enables the selected

device to drive the bus.

O3.3V LVTTL

PerPar0

External peripheral data bus byte parity.

I/O

3.3V LVTTL

PerReady

Used by a peripheral slave to indicate it is ready to

transfer data.

I3.3V LVTTL

PerR/W

Used as output by the peripheral controller. High

indicates a read from memory, low indicates a write to

memory.

O3.3V LVTTL

PerWE

Write Enable.

3.3V LVTTL

PerClk

Peripheral clock used by synchronous peripheral slaves.

3.3V LVTTL

PerErr

External error used as an input to record external slave

peripheral errors.

Notes:

1. Receiver input has hysteresis

2. Must pull up (recommended value is 3k

Ω to 3.3V)

3. Must pull down (recommended value is 1k

Ω)

4. If not used, must pull up (recommended value is 3k

Ω to 3.3V)

5. If not used, must pull down (recommended value is 1k

Ω)

6. Strapping input during reset; pull-up or pull-down required
