Function Documentation

aiclk_busy_handler()

uint8_t aiclk_busy_handler ( const union request * request, struct response * response )

static

Handles the request to set AICLK busy or idle.

Parameters

[in]	request	The request, of type aiclk_set_speed_rqst_t, with command code MSG_TYPE_AICLK_GO_BUSY to go busy, or MSG_TYPE_AICLK_GO_LONG_IDLE to go idle.
[out]	response	The response to the host

Returns
