Register of ADV8005 OSD Core Enable reg_osd_enable , mention in HW manual page 172, 0xEE00
In page 25, register map architecture and other description, 0xEE00 belong to Tx1 EDID map. @
So are there something wrong?
on software manual, don't find this reg_osd_enable bit, it is strange! need the ADV8005 expert to double check!
i had checked with expert:OSD (including OSD core enable) belongs to SPI interface. It’s not I2C address (like TX1 EDID map).
you can also see the description on ADV8005 hardware user guide:
As outlined in Section 4.1.2, the OSD core in the ADV8005 is controlled mainly via a SPI slave interface and loads images and OSD data into the part via a SPI master interface. Consequently, a number of the configuration registers for the OSD core are SPI registers and the code required to control these registers is automatically generated by the Blimp OSD software tool – abstracting the user away from having to understand them. For this reason, many of the SPI registers are not described in this section. For more information, refer to the Blimp OSD software tool user manual.
