Function metro_m0::spi_master

pub fn spi_master(
    clocks: &mut GenericClockController,
    baud: Hertz,
    sercom4: SERCOM4,
    pm: &mut PM,
    sclk: impl Into<Sclk>,
    mosi: impl Into<Mosi>,
    miso: impl Into<Miso>
) -> Spi

Convenience for setting up the 2x3 header block for SPI. This powers up SERCOM4 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.
