 * Hardware Abstraction Layer (HAL) is an abstraction layer, between the physical hardware and the tinyusb stack.
 * Its function is to hide differences in hardware from most of MCUs, so that most of the stack code does not need to be changed to
 * run on systems with a different MCU.
 * HAL are sets of routines that emulate some platform-specific details, giving programs direct access to the hardware resources.
