Initially, Bert Van Den Berg said:
After searching the Tutorials section and 8052 FAQS I am still not positive what happens to the internal RAM of an 8051 after a hardware reset. I did find the statement "Internal RAM is volatile, so when the 8051 is reset this memory is cleared". Then, Bert Van Den Berg said:
The final answer - the internal 128/256 bytes of user SRAM is not affected by the hardware reset. [my emphasis] Note that, If you are programming in 'C', your compiler's default startup code may initialise some or all of the available RAM (DATA, IDATA, and/or XDATA) - see your compiler's documentation for details. |
