2.1 Module configuration
The ShARC-XP has a large number of jumper links of which two sets are user adjustable.
The remainder jumper links are factory set and should not be reconfigured by the user, as
it is likely to result in the board malfunctioning. Where there is an NTSC requirement to
place closed caption data on lines 20/21 the ShARC-XP can leave these lines
unprocessed.
