IDATA, PDATA and XDATA

Rick meyer67138

Hello everyone,

 

Im programming applications for the CC1110 SoC at the moment and Im wondering what the different stacks are for. I know that XDATA  is a 16-bit read/write data memory
space from the datasheet of the CC1110 and that this is the place where the declared variables are stored. But when I look in the projekt options of my projekt I see IDATA and PDATA in the Stack/Heap section too.

My question is what is IDATA and PDATA and are they really on my hardware because I couldnt find them in the Datasheet

 

Thanks in advance

    Hi

    IDATA is internal indirectly addressable RAM (Fast access RAM, 256 bytes large).
    PDATA is paged data in the XDATA area. This memory is indirectly accessed using 8-bit addresses and is one 256-byte page large.
