VLANPrMap0
I/Opu VLAN priority mapping
This configuration chooses between 4 hard-wired mapping schemes
for the associations of VLAN priority within the received packet and
one of the 4 priority levels set by PriClass. The resolution function is
used for the final priority class if the receiving port already has a
priority level assigned by PriClass configuration, or the VLAN
prioritization is active.
VLANPrMap(0)is latched on reset.

FcBcstMode
I/Opd
This pin changes the flow control threshold’s behaviour if pin 160 is
set to logic 1 (It enables broadcast function).
'1' – only the flow control threshold on the broadcast queue is considered
'0' – flow control thresholds associated to each source port originating the
broadcast frames are considered FCBcstMode is latched on reset.

FcBcstEn
I/Opd
Enables/disables flow control for broadcast packets.
'1' – enabled
'0' – disabled
FcBcstEn is latched on reset.
