Name Description
0Ð3
TEHS
Transmit extra header size. Used only in user-deÞned cell mode to hold the Tx user-deÞned
cellsÕ extra header size. Values between 0-11 are valid. TEHS = 0 generates 1 byte of extra
header; TEHS = 11 generates 12 bytes of extra header.
4Ð7
REHS
Receive extra header size. Used only in user-deÞned cell mode to hold the Rx user-deÞned
cellsÕ extra header size. Values between 0Ð11 are valid. For REHS = 0, the receiver expects 1
byte of extra header; for REHS = 11, it expects 12 bytes of extra header.

LAST PHY/
PHY ID
Last PHY. (Multiple PHY master mode only.) The UTOPIA interface polls all PHYs starting
from PHY address 0 and ending with the PHY address speciÞed in LAST PHY. (The number of
active PHYs are LAST PHY+1). LAST PHY should be speciÞed in both multiplex and direct-
polling modes.
PHY ID. (Multiple PHY slave mode only.) Determines the PHY address of the ATM controller
when conÞgured as a slave in a multiple PHY ATM port.
