C1-Public
Several GPIOs described in Table 22 , Table 23 , and Table 24 :
•
are connected to the pin headers by default and can’t be disconnected
•
are connected to the pin headers by default but can be disconnected
•
are not connected to the pin headers by default but can be connected
•
may be connected to the pin headers and other locations simultaneously
The right columns in Table 22 , and Table 23 show how to connect, disconnect, or disconnect
other locations related to each GPIO or function.
