DSP TMS320F28032 Microcontroller Flash Code Extraction needs to disable the fuse bit of tms320f28032 mcu flash memory by cracking technique, and recover embedded firmware from processor’s tms320f28032;

The PIE block serves to multiplex numerous interrupt sources into a smaller set of interrupt inputs. The  PIE block can support up to 96 peripheral interrupts. On the 280x, 43 of the possible 96 interrupts are  used by peripherals.

The 96 interrupts are grouped into blocks of 8 and each group is fed into 1 of 12 CPU interrupt lines (INT1 to INT12). Each of the 96 interrupts is supported by its own vector stored in a dedicated RAM block that can be overwritten by the user.

The vector is automatically fetched by the CPU on servicing the interrupt. It takes 8 CPU clock cycles to fetch the vector and save critical CPU registers which can be used for copy dsp mcu tms320f28030 flash program. Hence the CPU can quickly respond to interrupt events. Prioritization of interrupts is controlled in  hardware and software. Each individual interrupt can be enabled/disabled within the PIE block.
