3.7A/D Range and Status Read back Register

The A/D range setting and A/D FIFO status can be read back from this register.

Address: BASE + 8h

Attribute: read only

Data Format:

	Bit		7	6	5	4	3	2	1	0

	BASE+8h		AD_BUSY	FF_FF	FF_HF	FF_EF	0	G2	G1	G0
	BASE+9h		X	X	X	X	X	X	X	X
Where
	GC0~GC2:		A/D Range control setting
	FF_EF:		‘0’ means FIFO is empty
	FF_HF:		‘0’ means FIFO is half-full
	FF_FF:		‘0’ means FIFO is full, A/D data may have been loss
	AD_BUSY:		‘0’ means AD is busy, the A/D data has not been latched
			in FIFO yet. If AD_BUSY changes from ‘0’ to ‘1’, A/D is
			not busy and the data is written into FIFO.

3.8A/D Trigger Mode Control Register

This register is used to control the A/D trigger source and trigger method.

Address: BASE + 0Ah

Attribute: write only

Data Format:

Bit	7	6	5	4		3		2	1	0

BASE+0Ah	X	X	X	X		PTRG		EITS	TPST	ASCAN
BASE+0Bh	X	X	X	X		X		X	X	X
PTRG:	Pre-trigger ON/OFF control
	0: Pre-trigger OFF
	1: Pre-Trigger ON
EITS:	External / Internal Trigger Source
	1: External Trigger Source
	0: Internal Trigger Source
TPST:	Timer Pacer/ Software Trigger
	0: Software Trigger
	1: Timer Pacer Trigger
