/**
|
||||
* @brief Pinmux driver for ARM V2M Beetle Board
|
||||
*
|
||||
* The ARM V2M Beetle Board has 4 GPIO controllers. These controllers
|
||||
* are responsible for pin muxing, input/output, pull-up, etc.
|
||||
*
|
||||
* The GPIO controllers 2 and 3 are reserved and therefore not exposed by
|
||||
* this driver.
|
||||
*
|
||||
* All GPIO controller exposed pins are exposed via the following sequence of
|
||||
* pin numbers:
|
||||
* Pins 0 - 15 are for GPIO0
|
||||
* Pins 16 - 31 are for GPIO1
|
||||
*
|
||||
* For the exposed GPIO controllers ARM V2M Beetle Board follows the Arduino
|
||||
* compliant pin out.
