DIP Switches and Jumpers
DIP Switches and Jumpers
The following section describes the function of all of the jumpers and
switches on the EZ-Extender. Before connecting the extender, make sure
you understand each possible settings effect on your application.
Direction Control Switch (SW1)
The PPI interface is bidirectional and half-duplex. A designated DIP
switch, SW1 , provides an independent direction control for the DATA_A bus
and the sync signals ( FSYNC1 and FSYNC2 ) going to the camera interface
and ADC/mixed-signal HSC interface, as illustrated in Figure 2-1 on
page 2-2 . Each of the signals can be hardwired to be either transmit or
receive, or can be changed in real time using the PF0 processor program-
mable flag pin.
If the PF0 programmable flag is intended for direction control,
ensure the flag is not used for other purposes on the EZ-KIT Lite
board (the motherboard).
When the switch connects a direction control signal to ground ( GND ), the
corresponding signal (or signals) being controlled is an input.
The SW1 DIP switch settings are summarized in Table 2-1 through
Table 2-3 .
