Rev. 3.0
The 12K-byte FLASH memory from $1000 to $3FFF is for OSD font
storage. This OSD font memory stores up to 384 fonts, with each font
made up of 16 lines by 16 bits, i.e. 32 memory locations. The OSD fonts
memory can be accessed by CPU when the OSDMEN bit in the OSD
control register is clear. See
