LEDs and Pushbuttons
There are four LEDs and four pushbuttons connected to the NLP-5x’s IO ports. Refer to the chart for the IO
summary and allocations.
LED SW Default DIP Switch (S9)
The LED SW default DIP Switch (S9) is provided to allow each LED and pushbutton to be disconnected from
the NLP-5x IO pins so that the IO pins can be used for a different purpose. To disconnect them, place the
switches on the OFF positions.
Connector (CN9)
This connector is provided to interface with the external devices which will be connected to in parallel with LEDs
and switches.
Connector (CN8)
This connector is provided to connect different port pins to the LEDs and switches. To do this, place the LED
SW default DIP switch to the OFF position, and make connections with hook-up wires to CN8 from the CN3
connector.
Serial Memory ICs
We have provided one 32Mbit Serial Flash IC, AT45DB321D, (U23) and one 128Kbit Serial EEPROM, 24LC128
(U24). Their connections can be disconnected by Serial Memory DIP switch (S10) in the OFF position.
If you are going to connect an external device with a SPI interface:
Disconnect the on-board serial flash, or
Use a dedicated port pin for –CS signal for the external device.
Parallel Memory IC
We have provided one 32Mbit parallel memory IC, AT49BV322D (U2).
