UTOPIA Receive Cell Data Bus (RDAT[15:0]).
This data bus carries the ATM cells that are read
from the receive FIFO selected by RADR[4:0].
RDAT[15:0] is tri-stated when RENB is high.
RDAT[15:0] is tristated when RENB is high.
RDAT[15:0] is also tristated when either the null-
PHY address (0x1F) or an address not matching
the address space is latched from the RADR[4:0]
inputs when RENB is high.
RDAT[15:0] is updated on the rising edge of
RFCLK.
POS-PHY Receive Packet Data Bus (RDAT[15:0]).
This data bus carries the POS packet octets that
are read from the selected receive FIFO.
RDAT[15:0] is considered valid only when RVAL is
asserted.
RDAT[15:0] is tristated when RENB is high.
RDAT[15:0] is also tristated when either the null-
PHY address (0x1F) or an address not matching
the address space is latched from the RADR[4:0]
inputs.
RDAT[15:0] is updated on the rising edge of
RFCLK.
