DSP TMS320F28033 Microprocessor Heximal Code Extraction needs to recover embedded firmware from tms320f28033 flash memory and rewrite the heximal program to new tms320f28033 for MCU cloning;
The 280x supports three masked external interrupts (XINT1, XINT2, XNMI). XNMI can be connected to the INT13 or NMI interrupt of the CPU. Each of the interrupts can be selected for negative, positive, or both negative and positive edge triggering and can also be enabled/disabled (including the XNMI).
The masked interrupts also contain a 16-bit free running up counter, which is reset to zero when a valid interrupt edge is detected. This counter can be used to accurately time stamp the interrupt.
Unlike the 281x devices, there are no dedicated pins for the external interrupts. Rather, any Port A GPIO pin can be configured to trigger any external interrupt for copying dsp mcu tms320f28030 flash program.
The 280x can be clocked by an external oscillator or by a crystal attached to the on-chip oscillator circuit. A PLL is provided supporting up to 10 input-clock-scaling ratios.
The PLL ratios can be changed on-the-fly in software, enabling the user to scale back on operating frequency if lower power operation is desired. Refer to the Electrical Specification section for timing details. The PLL block can be set in bypass mode.
