Function Documentation

spi_slave()

void spi_slave	(	const spi_slave_callback_group_t *	spi_cbg,
		port_t	p_sclk,
		port_t	p_mosi,
		port_t	p_miso,
		port_t	p_cs,
		xclock_t	clk,
		int	cpol,
		int	cpha
	)

Initializes a SPI slave.

Note

Verified at 25000 kbps, with a 2000ns CS assertion to first clock in all modes. The CS to first clock minimum delay will vary based on the duration of the slave_transaction_started callback.

Parameters

spi_cbg	The spi_slave_callback_group_t context to use.
p_sclk	The SPI slave's SCLK port. Must be a 1-bit port.
p_mosi	The SPI slave's MOSI port. Must be a 1-bit port.
p_miso	The SPI slave's MISO port. Must be a 1-bit port.
p_cs	The SPI slave's CS port. Must be a 1-bit port.
clock_block	The clock block to use for the SPI slave.
cpol	The clock polarity to use.
cpha	The clock phase to use.
