PPI Direction Control (JP1)
The PPI direction control jumper ( JP1 ) is used when the board connects
to a Blackfin AV EZ-Extender. JP1 allows the GPIO signal PD7 to control
the direction of the PPI bus via a software flag. The default is positions 1
and 2. When connected to the extender, JP1 must be placed in positions 2
and 3.
