The following works in avr-gcc 5.4.0, but is not legal C++, because ptr's are not legal constexpr's:
constexpr auto *foo = ptr;
Workaround is to store the the address of the ptr in a uintptr_t and reinterpret_cast it at call site.
Workaround is to store the address of the ptr in a uintptr_t and reinterpret_cast it at call site.
The _SFR_ADDR macro in sfr_defs.h would give the address, but it does that by taking the address of the dereferenced
pointer and casts it to uint16_t, which is still not a legal constexpr.
The workaround therefore is to disable the pointer cast and dereference macro _MMIO_BYTE temporarily.
