TABLE 4-21: ACL INDIRECT REGISTERS FOR 14 BYTE ACL RULES (CONTINUED)
Address
Name
FORWARD Port Map
[4:0] Each bit indicates forwarding decision of one port.

Bit[0] = Port 1
Bit[1] = Port 2
Bit[2] = Port 3
Bit[3] = Port 4
Bit[4] = Port 5
When MD = 01 and ENB = 00,
Bit[4] is used as count unit:
0 = µs
1 = ms
Bit[3] is used to select count modes:
0 = count down in the 11-bit counter from an
assigned value in the Action field PM, P, RPE, RP,
and MM, an interrupt will be generated when
expired.
1 = count up in the 11-bit counter for every matched
packet received up to reach an assigned value in
the Action field PM, P, RPE, RP and MM, and then
an interrupt will be generated.
Note: See ENB field description for detail.
Port_ACL_C
ACL Port Register 12 (0x0C)
Reg. 110 (0x6E) Bits[7:5] = 010 for ACL, Reg. 110 Bits[3:0] = 0xn for Ports 1, 2, 3, 4, and 5.
Reg. 111 (0x6F) Bits[7:0] = Offset 0x0C to access the Indirect Byte Register 0xA0.
Location: (010 ACL) -> {0xn, offset} -> 0xA0 holds the data.
