Reserved bits. Write as 0.
Portmask for transmission of BPDU frames as defined in 5.10.6.4 page 44. When the management port
transmits a BPDU frame to the switch, it is forwarded to all ports in this portmask (bit16=port0, bit17=port1,
bit 18=port2).
Priority to use for transmitted management frames. Used to e.g. put a management frame in a high-priority
output queue for fast delivery.
Reserved bits. Write as 0.
If set, BPDU frames are discarded always. Setting has no effect, when the enable bit is set.
If set, all BPDU frames are forwarded exclusively to the management port specified in bits 3:0.
If cleared, BPDU frames are forwarded as any other frame, or discarded if the discard bit is set.
Set (latched) when a BPDU frame as defined in 5.10.6.4 page 44 was transmitted from the management
port to any output port. Bit is reset by writing into the register.
Reserved bits. Write as 0.
The Port number of the port that should act as a management port.
Relevant to all functions that forward frames to the management port (i.e. BPDU processing, snooping).
Note: It must be set 0 in this switch configuration (Port 0 to DMA0 is the management port).
