DQ1 I/O Ports of MC9S12G128
Some ports of the MC9S12G128 microcontroller have other functions besides being a general purpose I/O. Discuss the functions of each port of this microcontroller.
DQ2 Masking Techniques and Bit Addressability
Sometimes, we want to monitor only a few bits of an input port. Also, sometimes we want to send an output to only one bit of a port. Discuss some of the ways that we can achieve these objectives.

DQ1 Negative Number Representations
HCS12 uses 2’s complement representation for negative numbers. Discuss other techniques used for representing negative numbers inside CPUs. Talk about the advantage of 2’s complement over the other representations. Show some examples of how numbers are represented using each technique.
DQ2 Instructions Used for Signed and Unsigned Numbers
This week, we are talking about different instructions for signed and unsigned numbers. Discuss the carry, overflow, and N flag. How does CPU know if you are using a number as a signed number or as an unsigned number? Discuss the different instructions used for signed or unsigned numbers. For example, what is the difference between signed multiplication and unsigned multiplication? What is the difference between shifting a signed number and shifting an unsigned number
