ATM
: Transmit UTOPIA ATM Layer
Data Bits 7 to 0 form the byte-wide
data driven to the PHY layer. Bit 0 is
the Least Significant Bit (LSB). Bit 7
is the Most Significant Bit (MSB)
and is the first bit received for the
cell from the serial line.
Note that only the lower 8 bit of the
bus are used in ATM master mode.
PHY
: Receive UTOPIA/Any-PHY
PHY Layer Data Bits 15 to 0 form
the word-wide data driven to the
ATM layer. This bus is only driven
when the ATM layer has selected
the UI_SRC_INTF for a cell transfer.
The upper byte is only used if
16_BIT_MODE is set in the
UI_SRC_CFG register. Otherwise
the upper byte is driven to 0’s. Bit 0
is the LSB. Bit 7 is the MSB of the
first byte and is the first bit received
for the cell from the serial line.
TATM_PAR/ RPHY_PAR
Output D3
ATM
: Transmit UTOPIA ATM Layer
Parity is a byte parity bit covering
TATM_D(7:0).
PHY
: Receive UTOPIA/Any-PHY
PHY Layer Parity is either a byte
parity covering RPHY_D(7:0) or
word parity covering RPHY_D(15:0)
depending on the value of
16_BIT_MODE.
