2.3 PCL and PCLATH
The program counter (PC) is 13-bits wide. The low byte
comes from the PCL register, which is a readable and
writable register. The upper bits (PC<12:8>) are not
readable, but are indirectly writable through the
PCLATH register. On any RESET, the upper bits of the
PC will be cleared. Figure 2-5 shows the two situations
for the loading of the PC. The upper example in the figure
shows how the PC is loaded on a write to PCL
(PCLATH<4:0> → PCH). The lower example in the figure
shows how the PC is loaded during a CALL or GOTO
instruction (PCLATH<4:3> → PCH)..
