PIC Microcontroller and Embedded Systems: Using Assembly and C for PIC$18$

Instructions:

Please help to Write ONE$$ Write, Assemble and build ONE complete assembly program using the MPLAB IDE software based on the PIC$18$F$458$

$$architecture to perform the following tasks: complete assembly program to perform the following tasks:

a$.$ Set up and initialize the table pointer to point to an array of data stored in program memory, starting with the label The Data. The dataset contains a total of D$\text{'}256\text{'}$ elements, consisting of $8-$bit numbers represented in hexadecimal format.

b$.$ Create a program to count all negative values in TheData that are divisible by $4.$ Store the result in TOT$\_$EL$4$ at memory address $0$x$100.$

c$.$ Write an assembly source code for the assigned task and use the MPLAB assembler to generate the source code $($ASM$)$ file, listing $($LST$)$ file, and object code $($HEX$)$ file. Your program should start at address $0$x$450.$ Include sufficient comments to ensure your program is easy to understand

$$

Requirements:

$1)$ Your main program must start at address $0$x$000450.$ Make sure you include sufficient comments to make your program readable and understandable.

$2)$ For debugging purpose, in your assembly program, define a data section at the program memory AFTER your main program. The data section should be named TheData and consists of a dataset of D$256$ hexadecimal numbers. Please use the dataset below:
