PIC18C601/801
4.4
The program counter (PC) specifies the address of the
instruction to fetch for execution. The PC is 21-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<15:8>
bits and is not directly readable or writable. Updates to
the PCH register may be performed through the
PCLATH register. The upper byte is called PCU. This
register contains the PC<20:16> bits and is not directly
readable or writable. Updates to the PCU register may
be performed through the PCLATU register.
The PC addresses bytes in the program memory. To
prevent the PC from becoming misaligned with word
instructions, the LSb of the PCL is fixed to a value of ’0’.
The PC increments by 2 to address sequential instruc-
tions in the program memory.
The CALL,
instructions write to the program counter directly. For
these instructions, the contents of PCLATH and
PCLATU are not transferred to the program counter.

The contents of PCLATH and PCLATU will be trans-
ferred to the program counter by an operation that
writes PCL. Similarly, the upper two bytes of the pro-
gram counter will be transferred to PCLATH and
PCLATU by an operation that reads PCL. This is useful
for computed offsets to the PC (See Section 4.8.1).

The clock input (from OSC1 or PLL output) is internally
divided by four to generate four non-overlapping
quadrature clocks, namely Q1, Q2, Q3 and Q4. Inter-
nally, the program counter (PC) is incremented every
Q1, the instruction is fetched from the program memory
and latched into the instruction register in Q4. The
instruction is decoded and executed during the follow-
ing Q1 through Q4. The clocks and instruction execu-
tion flow are shown in Figure 4-6.
