Function Documentation

uint32_t dtm_init ( void )

Returns: DTM_SUCCESS on successful initialization of the DTM module.

uint32_t dtm_wait ( void )

Returns: Time counter, incremented every 625 us.

uint32_t dtm_cmd	(	dtm_cmd_t	cmd,
		dtm_freq_t	freq,
		uint32_t	length,
		dtm_pkt_type_t	payload
	)

Parameters

[in]	cmd	One of the DTM_CMD values (bits 14:15 in the 16-bit UART format).
