Hi,
how can I write bits to the SA<11:0> of the PC104 interface in C?
I know there are in8 and out8 functions
which address do i use to write to SA?

As I reply in your other cross-post what does SA stands for?
PC/104 Bus Interface
· Standard configuration provides base address selection through a rotary switch
· PC/104 signals connected to the FPGA:
Control: RESET, AEN, IOW, IOR
Address Data: SD<7:0>, SA<11:0>
IRQ: IRQ3, IRQ4, IRQ5, IRQ6, IRQ7, IRQ9, IRQ10, IRQ11,
IRQ12, IRQ14, IRQ15
DMA: DRQ0, DACK0, DRQ1, DACK1, DRQ2, DACK2, DRQ3,
DACK3, TC
I hope this makes it more clear
SA<11:0> is address data in this case
PC104 is the same as ISA only with more pins, I read this somewhere
I want to write to the address data
