STV0974
4.9.3.4 Firmware patching
4.10
The STV0974 has some firmware patching capabilities addressable through I
microprocessor interfaces through control registers firmware patch code downloads. Up to 15
different patches can be downloaded within a limit of 512 bytes of RAM.
The patch space starts from address 0x8600.
Patch structure:
“disable all patches”
“set address to patch”
“set offset of patch in memory”
“write patch in memory (starting from address 0x8600 + patch memory offset)”
“enable all patches”
The state in which to download the patch depends on the nature of the patch, most likely either idle
or sleep mode. Please contact ST support for patch delivery and recommendations for ideal use.
Additional features
There are a number of additional features which are supported by the STV0974, however
implementation of these features is not supported by this datasheet. Please contact the ST support
team for support of these features if you have a specific requirement.

The polarity of the HSYNC and VSYNC signal can be programmed. However, these are non-
standard settings.
The transmitted byte order of the RGB and YUV is programmable.
The viewfinder color matrix can be programmed to match the characteristics of a local LCD
display.
