MAC5 – CPU MAC address byte 5
INT_MASK0 – Interrupt Mask
INTP_MASK0 – Interrupt Mask for MAC Port 0,1
Port 0 statistic counter wrap around interrupt mask. An Interrupt is generated when a statistic
counter wraps around. Refer to hardware statistic counter for interrupt sources
Port 0 link change mask
Port 0 module detect mask
Reserved
Port 1 statistic counter wrap around interrupt mask. An interrupt is generated when a statistic
counter wraps around. Refer to hardware statistic counter for interrupt sources.
Port 1 link change mask
Port 1 module detect mask
Reserved
Bit [7:0]:
CPU frame interrupt. CPU frame buffer has data for CPU to read
Control Command 1 interrupt. Control Command Frame buffer1 has data for CPU to read
Control Command 2 interrupt. Control command Frame buffer2 has data for CPU to read
Reserved
Device Timeout Detected interrupt
Byte 5 of the CPU MAC address (Default 0)
