Control Command 1 interrupt. Control Command Frame buffer1 has data for CPU to read
Device Timeout Detected interrupt
CPU frame interrupt. CPU frame buffer has data for CPU to read
Control Command 2 interrupt. Control command Frame buffer2 has data for CPU to read
Reserved
Byte 2 (bits [23:16]) of the CPU MAC address (Default 0)
Byte 4 (bits [39:32]) of the CPU MAC address (Default 0)
Byte 5 (bits [47:40]) of the CPU MAC address (Default 0)
Note: Bits [42:40] are set on a per port basis using MAC01, MAC23, MAC45,
MAC67 registers. For port 9, this register is ignored and MAC9 is used for bits
[47:40].
