7 Vertical Parity

Field Definitions

pm         : pass and mark, reserved for diagnostics
ttk(x,y)   : x tracks with pt >= y
tel(x,y)   : x tracks with tight CPS match and pt >= y
tiq(x,y,z) : x isolated tracks with pt >= y in quadrant z
tis(x,y)   : x isolated tracks with pt >= y
tes(x,y)   : x isolated tracks with tight CPS match and with pt >= y
tht(x)     : doublet occupancy >= x%
tgv(8,x)   : total singlet occupancy < x
tgv(1,x)   : singlet occupancy in any one octant < x
tgv(4,x)   : sum of singlet occupancy in the lowest four octants < x
toc        : two or more octants with a maximum sector singlet count >= 10

Vertical Parity bits are calculated over frames 1-6.

Test Modes

00: normal operation (power on default)
01: set PM every crossing, all other terms = 0
02: set ttk(1,*) every crossing, all other terms = 0
03: set terms [15:0] every crossing, all other terms = 0
04: reserved
05: reserved
06: reserved
07: reserved
08: reserved
09: set PM on the first crossing of a turn, all other terms = 0
10: set ttk(1,*) on the first crossing of a turn, all other terms = 0
11: set terms [15:0] on the first crossing of a turn, all other terms = 0
12: reserved
13: reserved
14: reserved
15: reserved

Revision History

02 Nov 2005: created JTO
03 Jan 2006: added parity links
07 Jan 2007: updated trigger term names to firmware version 34
             and added trigger term descriptions
01 Oct 2007: update TOC and TGV terms.
