The DEMOJM has an option to connect two signals, PTE2 and PTE3, to the
Embedded Multilink for signal processing. The two signals are connected or
disconnected to IN0 or IN1 correspondingly via jumper P&E INPUT_EN (J28).
The DEMOJM has one Reset switch and one Reset LED associated with it.
These are enabled or disabled by the two corresponding jumper RESET_EN
(J29).
The logic analyzer inputs are marked on one side of the J28 jumper. The
inputs allow P&E’s PC-based logic analyzer application to display these
signals in real-time.
By installing both jumpers, the logic analyzer pins IN0 and IN1 will be
connected to PTE2 and PTE3 respectively.
By removing these jumpers IN0 and IN1 will be unconnected. The
user may connect these signals, via wires, to any other signals on the
processor which they wish to view on the PC.
Enables the corresponding switch. Each jumper may be individually
installed or removed. By default, all jumpers are installed to enable all
the switches.
