GPIO Switch Bank 1 (SW1) and 2 (SW2)
Note:
GPIO Switch Bank 1 and Switch Bank 2, labeled SW1 and SW2, are two sets of five slide
switches that set GPIO inputs to logic levels of high (switch to left) or low (switch to
right).
If the GPIO port is configured as an output, then the switch should always be to the left. If
there is an external device connected to P3, the switch should always be set to the left.
Each GPIO port can be used independently.
Notes:



These switches do not determine whether the GPIO is an input or output. That
is determined by the module software.
If GPIO is set to an output by software, switches must be set to the left (high).
These switches are used in conjunction with SW3 and SW4.
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 "GPIO" on page 37 for more information
