Recover DSP TMS320F28032 Microcontroller Flash Memory Firmware needs to firstly crack dsp tms320f28032 mcu security system by locating the security code;

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.

ochrana před čtením DSP TMS320F28032 mikrokontrolér vestavěný firmware flash paměti musí nejprve prolomit zamčený bezpečnostní systém čipu DSP TMS320F28032 MCU umístěním bezpečnostního bitu, poté extrahovat binární soubor nebo heximální data z mikroprocesoru TMS320F28032 a zkopírovat zdrojový kód na nový čip;

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 restoring tms320f28027 flash binary. 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.
