2.2.2.1
The Status register 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, as with any other register. If the Status reg-
ister 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 not
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)
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.
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
R/W-0
Note:
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.
R/W-0
RP1
R/W-0
RP0
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
000u u1uu (where u = unchanged).
It is recommended, therefore, that only BCF, BSF,
SWAPF and MOVWF instructions are used to alter the
Status register because these instructions do not affect
the Z, C or DC bits from the Status register. For other
instructions not affecting any status bits, see
Section 15.0 “Instruction Set Summary”.
Note:
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
The C and DC bits operate as a borrow
and digit borrow bit, respectively, in sub-
traction. See the SUBLW and SUBWF
instructions for examples.
