Copy Locked MCU PIC16HV785 Firmware from its memory which include flash and eeprom memory, and then clone IC program and data to other blank Microcontroller PIC16HV785 which will provide the same functions;
The User Signature Row is a seperate memory section that is fully accessible (read and write) from application software and external programming. The User Signature Row is one flash page in size, and is meant for static user parameter storage, such as calibration data, custom serial numbers, random number seeds etc. This section is not erased by Chip Erase, and requires a dedicated erase command. This ensures parameter storage during multiple program/erase session and On-Chip Debug sessions when extract mcu pic16c712 firmware.
The Flash Program Memory and EEPROM data memory is organized in pages. The pages are word accessible for the Flash and byte accessible for the EEPROM. Table 7-2 on page 14 shows the Flash Program Memory organization. Flash write and erase operations are performed on one page at the time, while reading the Flash is done one byte at the time. For Flash access the Z-pointer (Z[m:n]) is used for addressing. The most significant bits in the address (FPAGE) gives the page number and the least significant address bits (FWORD) gives the word in the page.
Table 7-3 on page 14 shows EEPROM memory organization for the XMEGA A1 devices. EEPROM write and erase operations can be performed one page or one byte at the time, while reading the EEPROM is done one byte at the time. For EEPROM access the NVM Address Register (ADDR[m:n]) is used for addressing. The most significant bits in the address (E2PAGE) gives the page number and the least significant address bits (E2BYTE) gives the byte in the page if the chip pic16c715 program being read.
The XMEGA A1 has a Direct Memory Access (DMA) Controller to move data between memories and peripherals in the data space. The DMA controller uses the same data bus as the CPU to transfer data. It has 4 channels that can be configured independently. Each DMA channel can perform data transfers in blocks of configurable size from 1 to 64K bytes. A repeat counter can be used to repeat each block transfer for single transactions up to 16M bytes. Each DMA channel can be configured to access the source and destination memory address with incrementing, decrementing or static addressing. The addressing is independent for source and destination address before locked mcu get copied.
When the transaction is complete the original source and destination address can automatically be reloaded to be ready for the next transaction. The DMAC can access all the peripherals through their I/O memory registers, and the DMA may be used for automatic transfer of data to/from communication modules, as well as automatic data retrieval from ADC conversions, data transfer to DAC conversions, or data transfer to or from port pins. A wide range of transfer triggers is available from the peripherals, Event System and software. Each DMA channel has different transfer triggers.
To allow for continuous transfers, two channels can be interlinked so that the second takes over the transfer when the first is finished and vice versa. The DMA controller can read from memory mapped EEPROM, but it cannot write to the EEPROM or access the Flash.
