Special Function Registers as Source/Destination

PCL as Source or Destination
Bit Manipulation
The Section 29. Instruction Set’s orthogonal instruction set allows read and write of all file regis-
ters, including special function registers. Some special situations the user should be aware of are
explained in the following subsections:
If an instruction writes to the STATUS register, 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 example, executing
CLRF STATUS will clear register STATUS, and then set the Z bit leaving 0000 0100b in the reg-
ister.
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, W register or register file f.
All bit manipulation instructions will first read the entire register, operate on the selected bit and
then write the result back (read-modify-write (R-M-W)) the specified register. The user should
keep this in mind when operating on some special function registers, such as ports.
Note:
Status bits that are manipulated by the device (including the interrupt flag bits) are
set or cleared in the Q1 cycle. So there is no issue with executing R-M-W instructions
on registers which contain these bits.
