#157091 - my take on multiple dptrs Responding to: ???'s previous message |
it seems to me that a few chips that are made with "limited I/O features" are made to get market share by having multiple dptrs (I believe there is one out there with 8).
It also seems to me that those that concentrate on "I/O features" are less likely to have multiple dptrs. one word re this: with 'intelligent coding' the many chips that have internal XRAM and a "P2 substitution SFR for movx @Ri" can often be made run very efficient by using that feature. However I see no possibility of a C compiler doing so since efficient use of this feature requires buffers located on page boundaries and fixed location of variables is totally foreign to C. Erik |

Calm down - it's perfectly valid and correct | 01/01/70 00:00 | |
