GPIO
The i.MX6 GPIO module provides general-purpose pins that can
be configured as either inputs or outputs, for connections to
external devices. In addition, the GPIO peripheral can produce
CORE interrupts. The device contains eight GPIO blocks and
each GPIO block is made up of 32 identical channels.
The device GPIO peripheral supports up to 256 3.3-V GPIO
pins. Each channel must be properly configured, since GPIO
signals are multiplexed with other interfaces signals. For more
information on how to configure and use GPIOs, please refer to
section 5.7. For additional details, please refer to section 27 of
the i.MX 6 APRM.
