Module Connections
Tab l e 4 details the solder pad connection definitions and available functions for each connection pad. The GPIO connections available
on the CYBT-2x305x-02 can be configured to any of the input or output functions listed in Table 5. Table 4 specifies any function that
is required to be used on a specific solder pad, and also identifies SuperMux capable GPIOs that can be configured using the
ModusToolbox device configurator.
