Hi... Multiple Interrupts in GPIO -I can configurate most than one GPIO Pin to generate a Interruption, All those pins had the interrupt vector of 23! To know which pin make the Interruption I must read the register IPR (Interrupt Pending Register). But I´m using the software Drivers of SDK with CW, and I don´t have acess to IPR value using ioctl-command driver. So, how can I do to acess to a specific register (to read or write to/from a variable) using C or ASM instructions. -The memory of DSP56f803EVM as Flas/Ram Program Memory and Flash/Ram data memory, To acess to Flash data memory, I must develop some functions to write in flsh memory, or CW suports some kind of notation to indicate that variable is stored in Flash Data Memory? Thanks Antonio Macedo

I don't know CW :( so you'll have to wait for somebody other to answer. Jan
