Attack DSP Microcontroller TMS320F241PG Flash Memory needs to open the silicon package of MCU and disable the security fuse bit, embedded firmware will be restored from dsp ic tms320f241pg memory and copy the binary to new MCU;
There is no power sequencing requirement needed to ensure the device is in the proper state after reset or to prevent the I/Os from glitching during power up or power down (GPIO19, GPIO26–27, GPIO34–38 do not have glitch-free I/Os).
No voltage larger than a diode drop (0.7 V) above VDDIO should be applied to any digital pin (for analog pins, this value is 0.7 V above VDDA) before powering up the device. Voltages applied to pins on an unpowered device can bias internal p-n junctions in unintended ways and produce unpredictable results.

Upon power up, SYSCLKOUT is OSCCLK/4. Because the XCLKOUTDIV bits in the XCLK register come up with a reset state of 0, SYSCLKOUT is further divided by 4 before it appears at XCLKOUT. XCLKOUT = OSCCLK/16 during this phase.
Boot ROM configures the DIVSEL bits for /1 operation. XCLKOUT = OSCCLK/4 during this phase. XCLKOUT will not be visible at the pin until explicitly configured by user code.
crackear la memoria flash del microcontrolador protector DSP TMS320F241PG necesita abrir el paquete de silicio de la MCU segura TMS320F241PG y desactivar el bit del fusible de seguridad, el firmware integrado del archivo binario o los datos heximales se restaurarán desde la memoria cifrada del microprocesador TMS320F241PG y se copiará el código fuente original a la nueva MCU;
After reset, the boot ROM code samples Boot Mode pins. Based on the status of the Boot Mode pin, the boot code branches to destination memory or boot code function.
If boot ROM code executes after power-on conditions (in debugger environment), the boot code execution time is based on the current SYSCLKOUT speed when attack dsp controller tms320f28053 flash memory.
The SYSCLKOUT will be based on user environment and could be with or without PLL enabled. Using the XRS pin is optional due to the on-chip POR circuitry. The internal pullup or pulldown will take effect when BOR is driven high.
