Gpio Switch Bank 1 (Sw1) And 2 (Sw2) - Digi Connect EM DC-EM02T-JT Hardware Reference Manual

About the development board

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

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
n
by the module software.
If GPIO is set to an output by software, switches must be set to the left (high).
n
These switches are used in conjunction with SW3 and SW4.
