//| """Hardware accelerated external bus access
//|
//| The I2CDevice and SPIDevice helper classes make managing transaction state on a bus easy.
//| For example, they manage locking the bus to prevent other concurrent access. For SPI
//| devices, it manages the chip select and protocol changes such as mode. For I2C, it
//| manages the device address."""
