The following macro can be used to set/reset GPIO port D pin 1 (PD1).
#define PD1(x) (*((volatile uint32_t*)(GPIOD_BASE+0x08))=x<<1)
PD12 is a macro that would ret/reset both pins PD1 and PD2.
#define PD12(x) (*((volatile uint32_t*)(GPIOD_BASE+0xnn))=x<<m)
where nn is a hexdecimal number and m is an integer.
What are the values of 0xnn and m?0%
