General Purpose IO (GPIO) Ports

User programmable bidirectional GPIO ports are pro-

vided. The GPIO ports can be used as typical digital IO

ports. The directionality of the GPIOs can be config-

ured through console commands. The GPIOs can also

be read or asserted using the console commands. The

digital input and output voltage levels are provided in

Table 1-7.
