4.2.2.1
The Status Register, shown in Register 4-1, contains
the arithmetic status of the ALU; the Reset status and
the bank select bits for data memory (SRAM).
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 dis-
abled. These bits are set or cleared according to the
device logic. Furthermore, the TO and PD bits are non-
writable. Therefore, the result of an instruction with the
Status Register as destination may be different than
intended.

Status Register
STATUS REGISTER (ADDRESS: 03h, 83h, 103h, 183h)
bit 7
IRP: Register Bank Select bit (used for indirect addressing)
1 = Bank 2, 3 (100h - 1FFh)
0 = Bank 0, 1 (00h - FFh)
RP1:RP0: Register Bank Select bits (used for direct addressing)
00 = Bank 0 (00h - 7Fh)
01 = Bank 1 (80h - FFh)
10 = Bank 2 (100h - 17Fh)
11 = Bank 3 (180h - 1FFh)
TO: Time out bit
1 = After power-up, CLRWDT instruction, or SLEEP instruction
0 = A WDT time out occurred
PD: Power-down bit
1 = After power-up or by the CLRWDT instruction
0 = By execution of the SLEEP instruction
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
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
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
Legend:
R = Readable bit
-n = Value at POR
Note:
R/W-0
IRP
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.

Preliminary
W = Writable bit
‘1’ = Bit is set
R-1
TO
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 are used to alter the
StatusRegister because these instructions do not affect
any Status bit. For other instructions, not affecting any
Status bits, see the “Instruction Set Summary”.
Note 1: The C and DC bits operate as a Borrow
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared

and Digit Borrow out bit, respectively, in
subtraction. See the SUBLW and SUBWF
instructions for examples.
