Standard Microsystems CRT9028/9128 Video Terminal Logic Controller
|
||||
|
||||
The CRT 9028 and CRT 9128 are single-chip terminal-oriented video
|
||||
processors. The two differ from each other in their bus protocol
|
||||
for accessing the address, data and status registers: the 9028 has
|
||||
separate RD and WR strobes for an 8051 or similar microcontroller,
|
||||
while the 9128 replaces these with DS and R/W inputs that are more
|
||||
Z8-oriented. A separate address/data bus connects to a 2Kx8 static
|
||||
RAM or similar as display memory.
|
||||
|
||||
The internal 128-character set is mask-programmed, as are all
|
||||
screen timings, with alternate vertical timings to allow operation
|
||||
at either 60 Hz or 50 Hz. Mask parameters also determine the
|
||||
polarity of the sync signals, the positioning of the underline
|
||||
attribute and cursor and the dot patterns used for 6-segment wide
|
||||
(block) graphics and 4-segment thin (line) graphics.

||||
