Status Register
This register contains the arithmetic status of the ALU,
the Reset status and the page preselect bit.
The Status register can be the destination for any
instruction, as with 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 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
000u u1uu
(where
u
= unchanged).
Therefore, it is recommended that only
BCF
,
BSF
and
MOVWF
instructions be used to alter the Status register.
These instructions do not affect the Z, DC or C bits from
the Status register. For other instructions which do
affect Status bits, see
Section 10.0 “Instruction Set
Summary”
.

GPWUF:
GPIO Reset bit
1
= Reset due to wake-up from Sleep on pin change
0
= After power-up or other Reset
CWUF:
Comparator Wake-up on Change Flag bit
(1)
1
= Reset due to wake-up from Sleep on comparator change
0
= After power-up or other Reset conditions.
Reserved
:
Do not use. Use of this bit may affect upward compatibility with future products.
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 (for
ADDWF
and
SUBWF
instructions)
ADDWF:
1
= A carry from the 4th low-order bit of the result occurred
0
= A carry from the 4th low-order bit of the result did not occur
SUBWF:
1
= A borrow from the 4th low-order bit of the result did not occur
0
= A borrow from the 4th low-order bit of the result occurred
C
: Carry/borrow bit (for
ADDWF
,
SUBWF
and
RRF
,
RLF
instructions)
ADDWF:
SUBWF:
1
= A carry occurred
1
= A borrow did not occur Load bit with LSb or MSb, respectively
0
= A carry did not occur
0
= A borrow occurred

Note 1:
This bit is used on the PIC10F204/206. For code compatibility do not use this bit on
the PIC10F200/202.
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
