We can crack locked microprocessor PIC16HV540 code, please view the locked microprocessor PIC16HV540 features for your reference:
I/O Memory: All peripherals and modules are addressable through I/O memory locations in the data memory space. All I/O memory locations can be accessed by the Load (LD/LDS/LDD) and Store (ST/STS/STD) instructions, transferring data between the 32 general purpose registers in the CPU and the I/O Memory of locked microprocessor code cracking.
The IN and OUT instructions can address I/O memory locations in the range 0x00 – 0x3F directly. I/O registers within the address range 0x00 – 0x1F are directly bit-accessible using the SBI and CBI instructions. The value of single bits can be checked by using the SBIS and SBIC instructions on these registers. The I/O memory address for all peripherals and modules in XMEGA A1 is shown in the “Peripheral Module Address Map” on page 54.
The 16HV540 devices has internal EEPROM memory for non-volatile data storage. It is addressable either in a separate data space or it can be memory mapped into the normal data memory space. The EEPROM memory supports both byte and page access if the code from locked microprocessor can be copied.
• Supports SRAM up to
– 512K Bytes using 2-port EBI
– 16M Bytes using 3-port EBI
Supports SDRAM up to
– 128M bit using 3-port EBI
Four code configurable Chip Selects
code configurable Wait State insertion
Clocked from the Peripheral 2x Clock at up to two times the CPU clock speed
The External Bus Interface (EBI) is the interface for connecting external peripheral and memory to the data memory space. The XMEGA A1 has 3 ports that can be used for the EBI. It can interface external SRAM, SDRAM, and/or peripherals such as LCD displays and other memory mapped devices.
The address space, and the number of pins used, for the external memory is selectable from 256 bytes (8-bit) and up to 16M bytes (24-bit). Various multiplexing modes for address and data lines can be selected for optimal use of pins when more or less pins is available for the EBI when the code from locked microprocessor being copied.
Each of the four chip selects has seperate configuration, and can be configured for SRAM, SRAM Low Pin Count (LPC) or SDRAM. The data memory address space associated for each chip select is decided by a configurable base address and address size for each chip celect.
For SDRAM both 4-bit SDRAM is supported, and SDRAM configurations such as CAS Latency and Refresh rate is configurable in code.
The EBI is clocked from the Peripheral 2x Clock, running up to two times faster than the CPU and supporting speeds of up to 64 MHz when crack locked microprocessor.
