Hi all:
Could anyone give me some detail about the following statement:
#define IOPDATA ((volatile unsigned *)(SYSCFG + 0x5008))
if I change the *IOPDATA = 0x0; then how many bit can I change . what data
width is the (volatile unsigned *)? if I want to use a 32-bit width pointer
how can I do it?
Thanks all.
