4.5 Output HBLANK/VBLANK Control and Polarity Adjustment
The HBLANK is the mux output of HSYNC and self-test horizontal pattern. The VBLANK is the mux output of
VSYNC, CVSYNC and the self-test vertical pattern. The mux selection and output polarity are S/W
controllable. The VBLANK output is cut off when VSYNC frequency is over 200Hz or 133Hz depends on
8MHz/12MHz OSC selection. The HBLANK/VBLANK shares the output pin with P4.1/ P4.0.
4.6 Self-Test Pattern Generator
This generator can generate 4 display patterns for testing purposes: positive cross-hatch, negative cross-
hatch, full white, and full black (shown in the following figure). It was originally designed to support the
monitor manufacturer in performing a burn-in test, or to offer the end-user a reference to check the monitor.
The generator's output STOUT shares the output pin with P4.2.
