18.2.11.9 CPUIRDAT - CPU INTERNAL RAM DATA REGISTER
The 3 data registers are used when CPU reads or writes the content of the specified entry. table
CPUIRDAT0
CPU Internal RAM Data register for Data[31:0]
Address:
h588
CPUIRDAT1
CPU Internal RAM Data register for Data[63:32]
Address:
h58C
CPUIRDAT2

Address:
h590
Access:
Non-Zero-Wait-State,
Direct Access,
Write/Read
The content is dependent as to the type of table, as describe follows.
Type = MC ID (6bits)
Bit [5:0]
MCID
multicast ID FIFO data output
(Note that up to 16 for this version.)
Bit [31:6]
Reserved
Type = VMAP Table (27 bits)
Bit [12:0]
VLAN Port Enable [12:0]
one bit for each Ethernet MAC Port
Identify the ports associated with each VLAN
0 = disable
1 = enable
Bit [25:13] VLAN Tag Enable [12:0]
one bit for each Ethernet MAC Port
