pub use hal::target_device as pac;

calibration	NVM Software Calibration Area Mapping
clock	Configuring the system clock sources. You will typically need to create an instance of `GenericClockController` before you can set up most of the peripherals on the atsamd51 device. The other types in this module are used to enforce at compile time that the peripherals have been correctly configured.
delay	Delays
gpio	Working with GPIO pins. The pins are associated with the PORT hardware. This module defines a `split` method on the `PORT` type that is used to safely reference the individual pin configuration. The IO pins can be switched into alternate function modes, which routes the pins to different peripherals depending on the mode for the pin. The pin configuration is reflected through the use of type states to make the interface (ideally, or at least practically) impossible to misuse.
pad
prelude	Import the prelude to gain convenient access to helper traits
pwm
sercom	Working with the SERCOM peripherals.
time	Time units
timer	Working with timer counter hardware
trng
watchdog

Pins	Maps the pins to their arduino names and the numbers printed on the board.

ResetCause represents the reason the MCU was reset.

i2c_master	Convenience for setting up the labelled SDA, SCL pins to operate as an I2C master running at the specified frequency.
reset_cause	Returns the cause of the last reset.
serial_number	Returns the serial number of the chip as an array of bytes. The serial number is only guaranteed to be unique if all 16 bytes are used.
spi_master	Convenience for setting up the 2x3 header block for SPI. This powers up SERCOM2 and configures it for use as an SPI Master in SPI Mode 0. Unlike the `flash_spi_master` function, this one does not accept a CS pin; configuring a pin for CS is the responsibility of the caller, because it could be any OutputPin, or even a pulled up line on the slave.
split_serial_number	Returns the serial number of the chip as 4 32-bit integers. The serial number is only guaranteed to be unique if all 128 bits are used.
uart	Convenience for setting up the labelled RX, TX pins to operate as a UART device running at the specified baud.
