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 reg-
ister 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.

PCL and PCLATH
Example 1 - Instruction with PCL as destination
Example 2 - GOTO Instruction
Example 3 - CALL Instruction
Example 4 - RETURN, RETFIE, or RETLW Instruction
Note: PCLATH is not updated with the contents of PCH.
