• Is offset of 30 in load and store instructions shows an exceptional case?
    Hello to all, I am working on ARM Cortex-M4 and the memory arrangement is the little endian. I have started working on the memory instructions and for that purpose, I have chosen the offset addressing...
  • Explanation of cycles on pre and post index-addressing in case of Load and Store instructions.
    Hello to all, I am working on Cortex-M4 and in order to implement the load and store instructions, I have chosen the pre and post-index addressing and the memory arrangement is little endian. Therefore...
  • VTOR: offset address configuration
    Core: Cortex-M4F Do I need to configure vector table offset address to 0xnnnn_n 000? In case of 0x3080(Flash region), the program jump to unexpected code. I think it is caused by mismatching between vector...
  • Variation in the current consumption due to memory address and offset value?
    Hello to all, I am trying to figure out the variation in current consumption as well as in clock cycles due to different memory regions and different offsets. During various experiments, I have found...
  • Cortex-M3: What happen to the stack pointer (sp) when setting VTOR?
    The first entry of the vector-table is the initial value for the stack-pointer. I'm asking me, will the stack-pointer be changed when VTOR was set? Thanks for any help! :-)
