Hi all,

I trying to evaluation on my development board.
I have one AHB Master and serveral AHB Slaves, one of AHB Slaves is loaced ouside my chip, so I pull up the all signal related AHB Bus interface to the Ball.

As everyone know, so many pins are needed, I'd like to share the ARM DATA Pins (HRDATA, HWDATA). Could you show me the reference or guideline to do it?

Thanks for reading!
 

Hi
Could you share with us, ARM specific architecture docs that came with your board
 

Above my quesiton was solved by controlled with hready and hwrite signal,
I was afraid of Burst operation and sequence Write/Read, but I am looking the hready for safe read/write.

If anyone inform to any my bug on my proposal, please let me know that.

Thanks,
