Preliminary Data Sheet
The STOPMODE parameter has in case of external synchronization a different meaning
(EXSYN=1). The STOPMODE parameter defines, which input display raster the OSC block expects
and which output pictures the SDA 9400 generates. In case of interlaced signals the field
information is also necessary. The SDA 9400 will detect the information itself. If the VEXT signal has
a rising edge in the first half of the line period a field A is detected, otherwise a field B. The SDA
9400 recognizes only the rising edge of the VEXT and the HEXT signal. Therefore the length of the
external signals are not relevant.
Field detection by external synchronization
Static operation modes for external synchronization
If STOPMODE=0, then the SDA 9400 expects an external interlaced signal with the raster
sequence
～～
and the SDA 9400 generates an output picture sequence ABAB.
