#161291 - UPSD3354 PDATA and C51 |
Does anyone know if PDATA is supported on this chip? I have run out of DATA and want to avoid going all the way out to XDATA for vars.
On page 30 of their pdf doc they talk about "External Indirect Addressing". First they say it is not supported but then give an example using it! Is this one of the chips that only supports PDATA in the first 256 bytes of XDATA or does it really not support it at all. Any one? |
