PC [program counter] is a register holding the address of
the instruction which needs to be executed next. Its used
to keep track of current execution point - this tracking is
necessary for various reasons and some of these reasons are:
1. While branching or looping destination address is
specified with respect to the current PC value.
2. While branching to a function call current Pc value is
pushed into the stack and retrieved back when retrunign
from the function-call.
3. PC value is strored when servicing an interrupt and
restored back after execution of ISR.
