Program Counter register and the amount of ROM memory

[impakt]

Hello all,
is there a interdependence between the size of PC register and the amount of ROM memory? Meaning, if PC is 16bit long, the amount of ROM memory can not be less than 2^16=64K ROM memory?

No there is no interdepence of OF PC register and ROM ...

but to to acess ROM there is dependency..............

for 16 bit register one can access a memory at a time is of 2^16 = 64 MB.. but that doesn't mean that ROM is resticted upto 64 MB.. but access is restricted to 64MB..........

@konarkk you may want to recalculate your 64MB
@impakt you can easily use below 64k memory, but would need banking techniques for above 64k

In these conditions, can my program be more than 64k, but without banking technics?
