Extract Xilinx Secured CPLD XC9536-7VQ44 Source Code needs to attack cpld xc9635 eeprom memory protection and copy jed file from encrypted cpld xc9536 chipset;

During interrupts and subroutine calls, the return address Program Counter (PC) is stored on the Stack. The Stack is effectively allocated in the general data SRAM, and consequently the Stack size is only limited by the total SRAM size and the usage of the SRAM. All user programs must initialize the SP in the Reset routine (before subroutines or interrupts are executed) similar to copy epm7032aeti40 cpld chip set eeprom memory file. The Stack Pointer (SP) is read/write accessible in the I/O space. The data SRAM can easily be accessed through the five different addressing modes supported in the AVR architecture.

The memory spaces in the AVR architecture are all linear and regular memory maps.

A flexible interrupt module has its control registers in the I/O space with an additional Global Interrupt Enable bit in the Status Register. All interrupts have a separate Interrupt Vector in the Interrupt Vector table. The interrupts have priority in accordance with their Interrupt Vector posi- tion. The lower the Interrupt Vector address, the higher the priority.

The I/O memory space contains 64 addresses for CPU peripheral functions as Control Regis- ters, SPI, and other I/O functions. The I/O Memory can be accessed directly, or as the Data Space locations following those of the Register File after extracting cpld epm7032vtc44 eeprom data, 0x20 – 0x5F. In addition, the XC9536 has Extended I/O space from 0x60 – 0xFF in SRAM where only the ST/STS/STD and LD/LDS/LDD instructions can be used.
