PCL and PCLATH
The program counter (PC) species 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.
Figure 2-9 shows the four situations for the loading of
the PC. Example 1 shows how the PC is loaded on a
write to PCL (PCLATH<4:0>
→ PCH). Example 2
shows how the PC is loaded during a GOTO instruction
(PCLATH<4:3>
→ PCH). Example 3 shows how the PC
is loaded during a CALL instruction (PCLATH<4:3>
PCH), with the PC loaded (PUSHed) onto the Top of
Stack. Finally, example 4 shows how the PC is loaded
during one of the return instructions where the PC is
loaded (POPed) from the Top of Stack.
