Omega Engineering OME-PIO-D96 manual I/O Address Map, Address Read Write

3.3The I/O Address Map

The I/O address of OME-PIO/PISO series card is automatically assigned by the main board ROM BIOS. The I/O address can also be re- assigned by user. It is strongly recommended not to change the I/O address by user. The plug & play BIOS will assign proper I/O address to each OME-PIO/PISO series card very well. The I/O addresses of OME- PIO-D96 are given as follows:

Address	Read	Write
Wbase+0	RESET\ control register	Same
Wbase+2	Aux control register	Same
Wbase+3	Aux data register	Same
Wbase+5	INT mask control register	Same
Wbase+7	Aux pin status register	Same
Wbase+0x2a	INT polarity control register	Same
Wbase+0xc0	read Port0	write Port0
Wbase+0xc4	read Port1	write Port1
Wbase+0xc8	read Port2	write Port2
Wbase+0xcc	×	Port0~Port2 configuration
Wbase+0xd0	read Port3	write Port3
Wbase+0xd4	read Port4	write Port4
Wbase+0xd8	read Port5	write Port5
Wbase+0xdc	×	Port3~Port5 configuration
Wbase+0xe0	read Port6	write Port6
Wbase+0xe4	read Port7	write Port7
Wbase+0xe8	read Port8	write Port8
Wbase+0xec	×	Port6~Port8 configuration
Wbase+0xf0	read Port9	write Port9
Wbase+0xf4	read Port10	write Port10
Wbase+0xf8	read Port11	write Port11
Wbase+0xfc	×	Port9~Port11 configuration
