4.2.2.1
STATUS Register
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.
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 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 Regis-
ter 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
the "Instruction Set Summary."
REGISTER 4-1:
STATUS REGISTER (ADDRESS 03h, 83h)
Note 1: Bits IRP and RP1 (STATUS<7:6>) are not
used by the PIC16C433 and should be
maintained clear. Use of these bits as
general purpose R/W bits is NOT recom-
mended, since this may affect upward
compatibility with future products.
2: 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.

bit 7
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, 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, 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:
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
’1’ = Bit is set
’0’ = Bit is cleared
x = Bit is unknown
