Table 15-2 lists the instructions recognized by the
MPASM assembler.
All instruction examples use the following format to rep-
resent a hexadecimal number:
where h signifies a hexadecimal digit.
To represent a binary number:
where b signifies a binary string.

15.1
The PIC17C4X’s orthogonal instruction set allows read
and write of all file registers, including special function
registers. There are some special situations the user
should be aware of:
15.1.1
If an instruction writes to ALUSTA, the Z, C, DC and OV
bits may be set or cleared as a result of the instruction
and overwrite the original data bits written. For exam-
ple, executing CLRF
ALUSTA, and then set the Z bit leaving 0000 0100b in
the register.
15.1.2
Read, write or read-modify-write on PCL may have the
following results:
Read PC:
Write PCL:
Read-Modify-Write:
Where PCH = program counter high byte (not an
addressable register), PCLATH = Program counter
high holding latch, dest = destination, WREG or f.
15.1.3
All bit manipulation instructions are done by first read-
ing the entire register, operating on the selected bit and
writing the result back (read-modify-write). The user
should keep this in mind when operating on special
function registers, such as ports.
