About the development board

Switches

The development board provides the following switches:

GPIO switch bank 1 (SW1) and 2 (SW2)

Reset switch (SW5)

This push button switch is labeled SW5. Pressing it sets the module's /RST line low, holding the module

in a hard reset until the switch is released.

Note

This is a "hard" reset using the /RST pin on the main connector, not a "soft" reset. The reset

button on the embedded module performs a "soft" reset (see also

Serial/GPIO switch bank 3 (SW3) and switch bank 4 (SW4)

Each switch bank holds five slide switches that enable either serial or GPIO signaling between the

development board and the module. When set for GPIO signaling, SW3 works in conjunction with SW1,

and SW4 works with SW2. See

following table for SW3 and SW4 switch definitions.

Note

These switches control where the development board routes a signal. They do not reconfigure

the NS7520 processor. Software should be configured to track with switch settings. See

more information.
