Table 192: Ethernet MAC Event Enable Register (Offset 0x408)

Description
Always 0.
When this bit is set, an attention will be asserted on an interesting packet
match.
Enable attention when transmit statistics block has overrun.
Enable attention when receive statistics block has overrun.
Enable attention when an Output Data Interface block has an overrun or
underrun.
Enable attention when the Auto-polling interface has an error.
Enable attention when the Management Interface is signaling an
interrupt.
Enable attention when the Management Interface transaction has
completed.
–
Enable attention when the link has changed state.

Table 193: LED Control Register (Offset 0x40C)

Description
If set, the blink rate for the Traffic LED is determined by the Blink
Period field (bit 30 to bit 9). This bit is reset to 1. If not set, the
blink rate assumes a Blink Period of 0x040, corresponding to
approximately 15.9 Hz.
Specifies the period of each blink cycle (on + off) for Traffic LED
in milliseconds. Must be a nonzero value.
For the BCM5906 only, this12-bit field is reset to 0x019, giving a
default blink period of approximately 15.9 Hz.
For all other devices, this is reset to 0x040, giving a default blink
period of approximately 15.9 Hz.

When this bit is set, the LED pins can be shared with a wireless
device which takes over when the link is lost.
–
link and blinks when there is traffic. (The LED_MODE field must
be set to 00 before enabling this bit.)
–
When this bit is set, the traffic LED blinks only when traffic is
addressed for the device. (The LED_MODE field must be set to
00 before enabling this bit.)
