3.3.4 Program Counter
The program counter (PC) shown in Figure 3-5 is a 16-bit register that
contains the address of the next instruction or operand to be fetched.
The five most significant bits of the program counter are ignored
internally and appear as 00000.
Normally, the address in the program counter automatically increments
to the next sequential memory location every time an instruction or
operand is fetched. Jump, branch, and interrupt operations load the
program counter with an address other than that of the next sequential
location.
