Commands

The status word “! ~XXXX~”, where XXXX are four hexadecimal digits, decodes as follows:

8000 =

Command complete

4000 =

Chip is busy

2000 =

Command completed without error

1000 =

Command aborted by an abort command

800 =

Late collision detected

400 =

Carrier lost

200 =

CTS lost

100 =

DMA underrun

80 =

Transmission deferred because link was busy

40 =

Collision detected during interframe spacing

 

(SQE/Heartbeat detected)

20 =

Excessive collisions

10 =

Reserved

The lowest nibble (bits 3 to 0) are a count of collisions during this transmission. For example:

~8802~ = Complete, Late collision, 2 collisions

~8841~ = Complete, Late Collision, SQE detected, 1 collision

The boot command display (using bfs) looks like this:

monitor:: boot
