Struct avr_hal_generic::spi::ChipSelectPin

pub struct ChipSelectPin<CSPIN>(/* private fields */);

Wrapper for the CS pin

Used to contain the chip-select pin during operation to prevent its mode from being changed from Output. This is necessary because the SPI state machine would otherwise reset itself to SPI slave mode immediately. This wrapper can be used just like an output pin, because it implements all the same traits from embedded-hal.
