Modules

ac	Analog Comparators
adc0	Analog Digital Converter 0
aes	Advanced Encryption Standard
ccl	Configurable Custom Logic
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.
cmcc	Cortex M Cache Controller
dac	Digital-to-Analog Converter
delay	Delays
dmac	Direct Memory Access Controller
dsu	Device Service Unit
eic	External Interrupt Controller
evsys	Event System Interface
freqm	Frequency Meter
gclk	Generic Clock Generator
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.
hal	A Hardware Abstraction Layer (HAL) for embedded systems
hmatrix	HSB Matrix
i2s	Inter-IC Sound Interface
icm	Integrity Check Monitor
mclk	Main Clock
nvmctrl	Non-Volatile Memory Controller
osc32kctrl	32kHz Oscillators Control
oscctrl	Oscillators Control
pac	Peripheral Access Controller
paste	The nightly-only concat_idents! macro in the Rust standard library is notoriously underpowered in that its concatenated identifiers can only refer to existing items, they can never be used to define something new.
pcc	Parallel Capture Controller
pdec	Quadrature Decodeur
pm	Power Manager
port	Port Module
prelude	Import the prelude to gain convenient access to helper traits
qspi	Quad SPI interface
ramecc	RAM ECC

rtc	Real-Time Counter
sdhc0	SD/MMC Host Controller
sercom	Working with the SERCOM peripherals.
sercom0	Serial Communication Interface 0
supc	Supply Controller
target_device	Peripheral access API for ATSAMD51J19A microcontrollers (generated using svd2rust v0.13.1)

time	Time units
timer	Working with timer counter hardware
trng	True Random Generator
usb	Universal Serial Bus
wdt	Watchdog Timer

Macros

dbgprint
define_pins	This macro is a helper for defining a Pins type in a board support crate. This type is used to provide more meaningful aliases for the various GPIO pins for a given board.

Enums

Interrupt

Enumeration of all the interrupts

Constants

NVIC_PRIO_BITS

Number available in the NVIC for configuring priority

Functions

i2c_master	Convenience for setting up the labelled SDA, SCL pins to operate as an I2C master running at the specified frequency.
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.
