The Frame Manager (FMan) supports several types of hardware ports:
|
|
Ethernet receiver (RX)
|
|
Ethernet transmitter (TX)
|
|
Offline/Host command (O/H)

Specifies the hardware port id.
|
|
Each hardware port on the FMan has its own hardware PortID.
|
|
Super set of all hardware Port IDs available at FMan Reference
|
|
Manual under "FMan Hardware Ports in Freescale Devices" table.
|
|
|
|
Each hardware port is assigned a 4KB, port-specific page in
|
|
the FMan hardware port memory region (which is part of the
|
|
FMan memory map). The first 4 KB in the FMan hardware ports
|
|
memory region is used for what are called common registers.
|
|
The subsequent 63 4KB pages are allocated to the hardware
|
|
ports.
|
|
The page of a specific port is determined by the cell-index.
