Oliver Sedlacek said:
#define timers (dual_timers *)0x03FF6000This defines a pointer to a variable of type dual_timer No, that's wrong. This casts the hex numeric literal to a pointer to the type "dual_timer" "dual_timer" probably defines a structure that models the registers of some memory-mapped peripheral. |
