This specification gives an overview of all registers.
The SAA8115HL is partly controlled via SNERT. The frame rate converter, the
SDRAM interface, the video formatter, the compression engine, the PPG, the SMP
and the audio functions are controlled via SNERT. This SNERT interface works
independently from the frame rate and can always be operated in the full frequency
range.
Via SNERT the following registers are accessible (see
