66
 
# File 'lib/katcp/client/roach.rb', line 66

def port=(p); set(8, (get(8) & 0xffff0000) | (p & 0xffff)); end

end

#xaui_bonded? ⇒ Boolean

Returns true if all four XAUI lanes are bonded

Returns:

  • (Boolean) 


82
 
# File 'lib/katcp/client/roach.rb', line 82

def xaui_bonded?; ((get(9) >> 6) & 1) == 1; end

#xaui_status ⇒ Object

Returns xaui status word. Bits 2 through 5 are lane sync, bit 6 is channel bonding status.



70
 
# File 'lib/katcp/client/roach.rb', line 70

def xaui_status; get(9); end

#xaui_status_ok? ⇒ Boolean

Returns true if all four lanes are sync’d and bonded.

Returns:

  • (Boolean) 


72
 
# File 'lib/katcp/client/roach.rb', line 72

def xaui_status_ok?; (get(9) & 0b01111100) == 0b01111100; end

#xaui_sync ⇒ Object

Four least significant bits represent sync status for each lane.

1 bit = lane sync OK
0 bit = lane sync BAD

Proper operation requires all four lanes to have good sync status, so 15 (0b1111) is the desired value.



78
 
# File 'lib/katcp/client/roach.rb', line 78

def xaui_sync; (get(9) >> 2) & 0b1111; end

#xaui_sync_ok? ⇒ Boolean

Returns true if #xaui_sync returns 15

Returns:

  • (Boolean)

# File 'lib/katcp/client/roach.rb', line 80

def xaui_sync_ok?; xaui_sync == 0b1111; end
