DESCRIPTION
TheSTV9425/25B/26is anONSCREENDISPLAY
for monitor. It is built as a slave peripheral con-
nected to a host MCU via a serial I
2
C bus. It
includesa displaymemory, controlsall the display
attributesand generatespixels 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. I
2
C interface allows MCU to make
transparent internal access to prepare the next
pagesduring the display of the current page. Tog-
glefrom onepage toanotherbyprogrammingonly
one register.
