DESCRIPTION
The STV9427/28/29 is an ON SCREEN DISPLAY
for monitor. It is built as a slave peripheral con-
nected to a host MCU via a serial I²C bus. It
includes a display memory, controls all the display
attributes and generates pixels from the data read
in its on chip memory. The line PLL and a special
slice interpolator allow to have a display aspect
which does not depend on the line and frame
frequencies. I²C interface allows MCU to make
transparent internal access to prepare the next
pages during the display of the current page. Tog-
gle from one page to another by programming only
one register.
