RATM_SOC/ TPHY_SOC

Input
W26
This signal has two definitions
depending on whether the UTOPIA
is in ATM mode or PHY mode.
ATM
: Receive UTOPIA ATM Layer
Start-Of-Cell is an active high signal
asserted by the PHY layer when
RATM_D contains the first valid byte
of a cell.
PHY
: Transmit UTOPIA/Any-PHY
PHY Layer Start-Of-Cell is an active
high signal asserted by the ATM
layer when TPHY_D contains the
first valid byte of a cell.
Any-PHY
: This pin is the Transmit
Start of Packet (TSOP) signal which
functions just like TPHY_SOC. This
signal is optional in this mode. If
unused, tie low.

ATM
: Receive UTOPIA ATM Layer
Data Bits 7 to 0 form the byte-wide
data from the PHY layer device. Bit
0 is the LSB. Bit 7 is the MSB. This
is the first bit of the cell, which will
be transmitted on the serial line.
The upper byte is not used in ATM
mode.
PHY
: Transmit UTOPIA/Any-PHY
PHY Layer Data Bits 15 to 0 form
the word-wide data from the ATM
layer device. Bit 0 is the LSB. Bit 7
is the MSB of the first byte. This is
the first bit of the cell, which will be
transmitted on the serial line. The
upper byte is only used if
16_BIT_MODE is set in the
UI_SNK_CFG register.
