PS30, Line 39: 	/* Complement bit (CMP) */
             : 	bool cmp_bit_present;
             : 	uint8_t cmp;
             : 
             : 	/* Sector/block protection bit (SEC) */
             : 	bool sec_bit_present;
             : 	uint8_t sec;
             : 
             : 	/* Top/bottom protection bit (TB) */
             : 	bool tb_bit_present;
             : 	uint8_t tb;
Something I didn't notice earlier: The `_present` flags are only consumed
when interpreting the range. And there, a `_present == false` is always
treated the same as if the bit itself is 0. So, AFAICS, the code would
still do the same if we'd drop the flags (if not present bits are 0
initialzed).

I guess that's a matter of taste. Leaner code vs. more explicit code.
