Workaround is to store the the address of the ptr in a uintptr_t and reinterpret_cast it at call site

For this to work we need to temporarily disable the _SFR_MEM8 macro so that the register macro just gives the address

For this the sfr_defs.h provides a macro which returns the address of a register
