FUNCTIONAL DESCRIPTION
(continued)
After the falling edge on V-SYNC, the first strip
descriptor is read at the top of the current table of
descriptors at the address given by P[9:0] (see
DISPLAYCONTROLregister).
If it is a spacing strip,SL[7:0] black or transparent
scan lines are displayed.
If it is a character strip, during CH[5:0] x (I + ZY)
scan lines (CH[5:0] given by the CHARACTER
HEIGHTregister), the charactercodes are read at
the addressesstarting from the1
st
onegiven bythe
descriptoruntil a endof line character or theend of
thescan line.
The nextdescriptoris thenread andthe same proc-
