PIC16C433
10.1
The PIC16C433’s orthogonal instruction set allows
read and write of all file registers, including special
function registers. There are some special situations
specified in the following sections the user should be
aware of.
10.1.1
If an instruction writes to STATUS, the Z, C and DC bits
may be set or cleared as a result of the instruction and
overwrite the original data bits written. For example,
executing CLRF STATUS will clear register STATUS,
and then set the Z bit leaving 0000 0100b in the
register.
10.1.2
Bit 3 of the TRIS register always reads as a '1' since
GP3 is an input only pin. This fact can affect some
read-modify-write operations on the TRIS register.

10.1.3
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.
10.1.4
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.
