Program Counter (PC)
The program counter (PC) specifies the address of the instruction to fetch for execution. The PC
is 13-bits wide. The low byte is called the PCL register. This register is readable and writable. The
high byte is called the PCH register. This register contains the PC<12:8> bits and is not directly
readable or writable. All updates to the PCH register go through the PCLATH register.
