Switches
The development board provides the following switches:
 Reset Switch (SW5)
 Serial/GPIO Switch Bank 3 (SW3) and Switch Bank 4 (SW4)
 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 "Main Connector (P8)" on page 24).
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 27 for more information. See the following table for SW3 and SW4
switch definitions.
