	Resumes a thread waiting for a conversion completion.
#define	_dac_reset_s(dacp)
	Resumes a thread waiting for a conversion completion.
#define	_dac_wakeup_isr(dacp)
	Wakes up the waiting thread.
#define	_dac_timeout_isr(dacp)
	Wakes up the waiting thread with a timeout message.
#define	_dac_isr_half_code(dacp)
	Common ISR code, half buffer event.
