Polled-PHY Transmit Packet Available: Transitions
high when a predefined (user programmable) number of
free words is available in the polled Tx FIFO. Once high,
it indicates that the polled Tx FIFO has a predefined
minimum
(SpaceAV_Threshold_Low) available. Transitions low
when the polled Tx FIFO has less than the predefined
minimum number of free words available. It is driven
when a matching PHY address is presented on PPUT-
TXADDR.
Tristated when either the null-PHY address or a not
matching PHY address is presented on PPUTTXADDR.
POS-PHY Standard notation: PTPA
Receive POS-PHY Clock: This clock is used for the
receive POS-PHY interface. The data and control sig-
nals are transferred on the rising edge of this clock.
Maximum clock frequency is 50 MHz.
POS-PHY Standard notation: RFCLK
Receive PHY Address Bus: In multi-PHY mode, these
leads indicate the address of the PHY being selected
and polled. Note that the null-PHY address is not
responded to. In single-PHY mode, this address is not
used and these leads must be tied to VSS.
POS-PHY Standard notation: RADR[4:0]
