Memory map file creation

We need to define the register address to Register name mapping.

This can be done by the following command

#define PORTB *((volatile unsigned char *) 0x25)

Once this is defined in the memorymap.h file, we can access the PORTB value directly by reading or writing to it with the name PORTB.

💡

It is important to remember that PORTB defined here is the de-referenced PORTB address. To access the PORTB address we need to add the reference & operator in front.

This process of defining the registers with their names will be done as the need arises.
