8-bit Microcontroller MEMORY Harvard Architecture -

Hi, How the memory is divided in a PIC-MICROCONTROLLER?
The PIC16F877A has 14-bit program memory addresses, allowing it to address up to 2¹⁴ = 16,384 (0x4000) memory locations.
The program memory is used to store the firmware or program that the microcontroller will execute.
The program memory is non-volatile, meaning the code remains intact even when power is removed.
The program memory is divided into multiple memory regions:
The lower region (0x0000 to 0x07FF) is typically used for the actual program code and interrupt vectors.
The upper region (0x0800 to 0x3FFF) is typically used for additional program code, constants, and calibration data.
The last part (0x4000 to 0xFFFF) is either unused or reserved for other purposes, as the PIC16F877A has a maximum program memory size of 8KB (0x2000).
