FREEDM 84A1024L ASSP Telecom Standard Product Data Sheet
Function
FREEDM 84A1024L will pause the data transfer and tri-state
the receive APPI outputs (except RPA) until RENB is returned
low. Since the Any-PHY bus specification does not support
deselecting during data transfers, the address on the
RXADDR[3:0] inputs during the cycle before RENB is returned
low must either re-select the same FREEDM 84A1024L device
or be a null address.
The polling function of the RXADDR[3:0] and RPA signals
operates regardless of the state of RENB.
It is the responsibility of the external controller to prevent
overflow by providing each FREEDM 84A1024L device on an
Any-PHY point to multi-point bus sufficient bandwidth through
selection.
Any-PHY Level 3 Mode:
RENB is used to throttle the FREEDM 84A1024L during data
transfer on Rx APPI. When the FREEDM 84A1024L samples
RENB high during data transfer, the FREEDM 84A1024L will
pause the data transfer until RENB is returned low.
