PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

Signal Name

Direction Pin No. Function

RSX

Output

POS-PHY Receive Start of Transfer

RSX indicates when the in-band port

address is present on the RDAT bus.

When RSX is high and RVAL is low, the

value of RDAT[0] is the address of the

receive FIFO to be selected by the

PM3386. Subsequent data transfers on

the RDAT bus will be from the FIFO

specified by this in-band address.

RSX is considered valid only when RVAL is

not asserted.

RSX is considered valid only when RENB

was asserted on the previous cycle.

RSX is updated on the rising edge of

RFCLK.

PAUSE Control

Assertion of the PAUSE0 or PAUSE1

signals may cause (programmed option)

the PM3386 on a per channel basis to

transmit 802.3-1998 PAUSE frames and

either drop at the MAC layer or pass to the

POS-PHY L3 client any further incoming

frames (programmed option). De-assertion

of the PAUSE0 or PAUSE1 signal can

cause the removal of the PAUSE condition

on a per channel basis.

Due to the programmability options for

these pins please see the PAUSE flow

control section in the Operations section.

PAUSE0 and PAUSE1 are active high

signals.

PAUSE0 and PAUSE1 are sampled on the

rising edge of the RFCLK.
