STATUS Register
The STATUS register, shown in Figure 4-2, contains
the arithmetic status of the ALU, the RESET status and
the bank select bits for data memory.
The STATUS register can be the destination for any
instruction, like any other register. If the STATUS
register is the destination for an instruction that affects
the Z, DC or C bits, then the write to these three bits is
disabled. These bits are set or cleared according to the
device logic. Furthermore, the TO and PD bits are not
writable. Therefore, the result of an instruction with the
STATUS register as the destination may be different
than intended.
For example,
CLRF STATUS will clear the upper-three
bits and set the Z bit. This leaves the STATUS register
as 000uu1uu (where
u = unchanged).
It is recommended, therefore, that only
BCF, BSF,
SWAPF and MOVWF instructions be used to alter the
STATUS register because these instructions do not
affect any status bits. For other instructions, not affect-
ing any status bits, see the “Instruction Set Summary”.
REGISTER 4-1:
STATUS REGISTER (ADDRESS 03h OR 83h)
Note 1: The IRP and RP1 bits (STATUS<7:6>)
are not used by the PIC16C55X and
should be programmed as ’0'. Use of
these bits as general purpose R/W bits is
NOT recommended, since this may affect
upward compatibility with future products.
2: The C and DC bits operate as a Borrow
and Digit Borrow out bit, respectively, in
subtraction. See the
SUBLW and SUBWF
instructions for examples.

IRP: Register Bank Select bit (used for Indirect addressing)
1
= Bank 2, 3 (100h - 1FFh)
0
= Bank 0, 1 (00h - FFh)
The IRP bit is reserved on the PIC16C55X, always maintain this bit clear
bit 6-5
RP1:RP0: Register Bank Select bits (used for Direct addressing)
11
= Bank 3 (180h - 1FFh)
10
= Bank 2 (100h - 17Fh)
01
= Bank 1 (80h - FFh)
00
= Bank 0 (00h - 7Fh)
Each bank is 128 bytes. The RP1 bit is reserved on the PIC16C55X, always maintain this bit clear.
bit 4
TO: Timeout bit
1
= After power-up, CLRWDT instruction, or SLEEP instruction
0
= A WDT timeout occurred
bit 3
PD: Power-down bit
1
= After power-up or by the CLRWDT instruction
0
= By execution of the SLEEP instruction
bit 2
Z: Zero bit
1
= The result of an arithmetic or logic operation is zero
0
= The result of an arithmetic or logic operation is not zero
bit 1
DC: Digit carry/borrow bit (ADDWF,
ADDLW,
SUBLW,
SUBWF
instructions) (for borrow the polarity is
reversed)
1
= A carry-out from the 4th low order bit of the result occurred
0
= No carry-out from the 4th low order bit of the result
bit 0
C: Carry/borrow bit (ADDWF, ADDLW,SUBLW,SUBWF instructions)
1
= A carry-out from the Most Significant bit of the result occurred
0
= No carry-out from the Most Significant bit of the result occurred
Note
1: For borrow the polarity is reversed. A subtraction is executed by adding the two’s complement of the second
operand. For rotate (RRF, RLF) instructions, this bit is loaded with either the high or low order bit of the
source register.
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
- n = Value at POR reset
’1’ = Bit is set
’0’ = Bit is cleared
x = Bit is unknown
