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.
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 register
as 000u u1uu (where u = unchanged).

1 = Bank 2, 3 (100h - 1FFh)
0 = Bank 0, 1 (00h - FFh)
RP1
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
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: Maintain the IRP and RP1 bits clear.

It is recommended that only BCF, BSF, SWAPF and
MOVWF instructions be used to alter the STATUS regis-
ter. These instructions do not affect the Z, C or DC bits
in the STATUS register. For other instructions which do
not affect status bits, see the "Instruction Set Sum-
mary."
