Details:
used definition (example):
typedef struct
{
uint8_t b_bit0 : 1;
uint8_t b_bit1 : 1;
uint8_t b_bit2 : 1;
union
{
uint8_t b_union0 : 1;
uint8_t b_union1 : 1;
};
uint8_t reserve : 4;
} _T_bitfield;
_T_bitfield bitfield;
bitfield.b_union1 = 1; // does not work! Bit number 4 will not be set to 1.
The asm - code initialise the worng Byteadress.
