; VSC supports several displays that are in the ÒextendedÓ sense line range. Since the raw
|
|
; values that come back from doing the extended sense-line algorithm do not map into a nice
|
|
; tablular form like the ÒnormalÓ sense line codes do, we map the few extended-sense-line displays
|
|
; that we support into the bottom of the normal sense line table.
|
|
;
|
|
; Notes: The ÒnormalÓ sense displays fall in the range of 0..7, where 7 means Ògo try the
|
|
; extended sense codes.Ó So, we map the extended sense codes from 8 (yeah, we have
|
|
; blank entry).
|
|
;
|
|
; Radius exploits the fact that the extended sense algorithm is generally only tried
|
|
; when a 7 is read back. That is, for their two TPD displays (one color, the other
|
|
; monochrome), they use 3 as the trigger for doing the extended sense algorithm. To
|
|
; distinguish the two displays from each other, they just reverse the polarity of the
|
|
; the diode on sense lines b & c. (Note: This technique could be used for sense
|
|
; codes 5 and 6, too.)
|
|
;
|
|
; So, it should be noted, that there are four types of extended sense codes. We
|
|
; just use types 3, 6, and 7; type 5 is reserved.
