No, pic16f877A is powered by a 8 bits pic core. the 877A is an upgrade for the 877 version. same for the sister microcontroller pic16f876A and pic16f876. I ve been fan of this microcontroller for years. It is powerful and you can do a lot of thing with it. You can you can have it from www tmartis com together with many other stuff that you can purchase together. I always do my purchases from there. Have fun
mov r1r2 is invalid instruction because of there is no communication with ALU in its operation;
The PIC16F877A microcontroller has 13 address lines, which allows it to address 8K words of program memory. This enables it to access a range of memory locations for storing instructions. Additionally, it has 368 bytes of data RAM and 256 bytes of Electrically Erasable Programmable Read-Only Memory (EEPROM) for data storage.
mov H , L mov is opcode H L are operands
1byte instruction = MOV A,B 2byte instruction = MVI A,01H 3byte instruction = STA 2030H

Syntax error: incomplete instruction.
To store the value 0ABH in external RAM at address 9A00H, you would typically use the following instruction sequence in assembly language for a microcontroller like the 8051. First, load the address into the DPTR register with MOV DPTR, #9A00H. Next, move the value 0ABH into the accumulator with MOV A, #0ABH. Finally, use MOVX @DPTR, A to transfer the value from the accumulator to the specified external RAM address.
The full form of MOV is "Move." In programming, MOV is an instruction that moves data from one location to another within the computer's memory or between different components of the computer.
