Functions
void	SSP0_IRQHandler (void)

void	SSP1_IRQHandler (void)

void	ssp_ssel_control (uint8_t id, uint8_t state)
	Function that controls the Slave Select (SSEL) signal This pin is controlled manually because the internal SSP driver resets the SSEL pin every 8 bits that are transfered.

void	ssp_init (uint8_t id, uint32_t bitrate, uint8_t frame_sz, bool master_mode, bool poll)

void	ssp_write_read (uint8_t id, uint8_t tx_buf, uint32_t tx_len, uint8_t rx_buf, uint32_t rx_len, uint32_t timeout)

Variables
