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 "GPIO Switch Bank 1 (SW1)
and 2 (SW2)" on page 34 for more information. See the following table for SW3 and SW4
switch definitions.
Note:
reconfigure the NS7520 processor. Software should be configured to track with switch
settings. See "GPIO" on page 39 for more information
These switches control where the development board routes a signal. They do not
