Description
ATM Transmit Data (7 4 :0). When the ATM port is enabled, this bus
carries the ATM cell octets, written to the PM5384’s transmit FIFO.
This bus is considered valid only when ATMTXEN# is asserted
and are sampled on the rising edge of ATMTFCLK.
When the ATM port is disabled, these lines may be used for any
available respective function.

I/O, T.S.
ATM Receive Data (7 4 :0). When the ATM port is enabled, this bus
carries the cell octets, read from the PM5384 receive FIFO. This
lines are updated on the rising edge of ATMRFCLK 3 .
When the ATM port is disabled, these lines are tristated and may
be used for any available respective function.
