Commodore 64 Zero Page. Processor port data direction register. 0 = bit #x in processor port can only be read; asked may 23, 2022 at 16:57. Commodore 64 uses almost 99% of it. 1 = bit #x in. in most computers based on 6502 and 6510 processors the first 256 bytes of memory are precious. Most instructions using this part of memory are shorter and faster to execute. the advantage to using zero page is that it uses 1 byte less than absolute addressing and it is 1 cycle faster, if you are worried about such things. Frankly, i think #5 kills it. There are so few free addresses to choose from that its practically guaranteed that something else will (eventually). the zero page the newsktter oft he. commodore 64 memory map. considering zero page, there are important addressing modes, like well known: Lda (fb),x which provides indirect memory addressing using fb and fc, and indexed with x in addition to that. Zeropage addressing is an addressing mode similar to absolute addressing, but limited in the sense that it can only refer to addresses within the zeropage, i.e.
