Clock input used to synchronize
transmitted data. Schmitt trigger input.
Enables data transmission when asserted
low. Schmitt trigger input.
Address of the PHY device being selected
for transmission. Address 1111 (31
decimal) indicates a null PHY port.
Schmitt trigger input.
Transmit data from the ATM layer.
Schmitt trigger input.
Parity calculated over the UTxData bus.
BusWidth (bit 0) in the IOMODE register
(0x0202) determines whether parity is
checked over UTxData[7:0] or
UTxData[15:0]. OddEven (bit 2) in the
UTOP1 register (0x0D) determines
whether this pin represents even or odd
parity. Schmitt trigger input.
Indicates the first byte of valid cell data
transmitted when asserted high. Schmitt
trigger input.
Indicates a FIFO full condition or Cell
Available condition, depending upon
UTOPIA HandShake (bit 1) in the
SYSBUS register (0xE01). An external
pulldown resistor is required for this pin.
Clock input used to synchronize received
data. Schmitt trigger input.
Enables data reception when asserted
low. Schmitt trigger input.
