Question

1.For the PIC18F452, how many bits represent an “unsigned char” data type?

2. Describe the DATA memory structure of the PIC18F452. What is a bank?How many banks are there? How many banks do we have access to in our programs?

3.Describe the PROGRAM memory structure of the PIC18F452. How much memory is available to store our code? What is the size of an instruction word? How many address bits do we need to access the available memory?

4. What are special function register (SFR) used for and where are they located in the PIC18F452?

5. How much memory in Mbytes can be accessed by using 16 bits for addressing assuming 8 bits ( or 1 byte) capacity for each memory location.

Explanation / Answer

The Asnwer to question 1 is as follows:

PIC18F452, the number of bits represent an “unsigned char” data type is 8 bits
