The FID/GLCO/VLK/HVLK and INTREQ/GPCL/VBLK pins are muxed differently depending on whether the input is an S-Video or composite signal. The comment that explains the logic doesn't reflect the code. It appears that the comment is incorrect, as disabling the output data bus in composite mode makes no sense. Update the comment to match the code. While at it define macros for the MISC_CTL register bits, the code is too confusing with numerical values.
