#define READ_SREG_INTO	(		avr,
			dst
	)

Value:

{       \
    dst = 0;                    \
    for (int i = 0; i < 8; i++)         \
      if (avr->sreg[i] > 1)         \
    printf("** Invalid SREG!!\n");      \
      else if (avr->sreg[i])            \
    dst |= (1 << i);            \
  }

Reconstructs the SREG value from avr->sreg into dst.

#define SET_SREG_FROM	(		avr,
			src
	)

Value:

{           \
    for (int i = 0; i < 8; i++)             \
      avr_sreg_set(avr, i, (src & (1 << i)) != 0);  \
  }

Splits the SREG value from src into the avr->sreg array.
