C++ (Cpp) ssp_read_word Examples

Example #1

// Send a command and drain the receive buffer.
static u32
ssp_putget(struct ad7877 *ad, u32 data)
{
	u32 ret;
	ssp_write_word(&ad->ssp, data);
	ssp_read_word(&ad->ssp, &ret);
	return ret;
}

Example #2

{
	u32 ret;

	ssp_write_word(&palmtt3_ssp_dev, command | read);
	ssp_read_word(&palmtt3_ssp_dev, &ret); /* Dummy read */
