Omega 1002 manual I/O Address Map

3.2 The I/O Address Map

The OME-PCI-1002 registers are given below. The address of each register is determined by adding the offset to the base address of the corresponding section.

Section	Offset	Name	Access	Length
1	4ch	PCI interrupt control	R/W	8/16/32 bits
		register
	00h	8254 timer1	R/W	8/16/32 bits
	04h	8254 timer2	R/W	8/16/32 bits
	08h	8254 timer3	R/W	8/16/32 bits
	0Ch	8254 control register	W	8/16/32 bits
	10h	Analog input channel	W	8/16/32 bits
		control register
2	10h	Status register	R	8/16/32 bits
	14h	Analog input gain	W	8/16/32 bits
		control register
	18h	General control		8/16/32 bits
		register	W
	1Ch	A/D software trigger	W	8/16/32 bits
	1Ch	Clear Interrupt	R	8/16/32 bits
	20h	Digital output register	W	16/32 bits
	20h	Digital input register	R	16/32 bits
