2, the ATM device polls PHY device 'N'. On clock edge 3, PHY device 'N' indicates to the ATM device that it has a
complete cell ready for transfer by asserting RPXA. On clock edge 4, the ATM device selects PHY device 'N'. On
clock edge 5, the ATM device asserts REN. On clock edge 6, PHY device 'N' starts a cell transfer by placing the
first byte of cell data on RDATA, and asserting RSOX to indicate the transfer of the first byte of the cell. On clock
edge 7, PHY device 'N' de-asserts RSOX as it continues to place additional bytes of the cell on RDATA. On clock
edge 12, the ATM device polls PHY device 'O'. On clock edge 13, PHY device 'O' indicates to the ATM device that
it has a complete cell ready for transfer by asserting RPXA. On clock edge 16, the ATM device deselects PHY
device 'N' and selects PHY device 'O' by de-asserting REN and placing PHY device 'O's address on RADR. On
clock edge 17, the ATM device asserts REN and PHY device 'N' stops transferring cell data and tri-states its
RDATA and RSOX outputs. On clock edge 18, PHY device 'O' starts a cell transfer by placing the first byte of cell
data on RDATA, and asserting RSOX to indicate the transfer of the first byte of the cell. On clock edge 19, PHY
device 'O' de-asserts RSOX as it continues to place additional bytes of the cell on RDATA.
