• Manufacturer Part Number: tmc22051
• Description: Multistandard Digital Video Decoder Three-line Adaptive Comb Decoder Family, 8 & 10 Bit
• Manufacturer: Cadeka Microcircuits LLC.

*Note:
To read from the XLUT, the initial read must be a dummy read. This means, for example, to read back XLUT location 0x02, read
back location 0x01, then read back 0x02 and ignore the information read back from the 0x01 location. This only needs to be done
once in a sequence. To read back the entire XLUT, set the pointer to 0xFF and ignore the data read from this register. The pointer
will then auto-increment to 0x00 allowing the next 256 locations read to be valid.
