AND
And Wb and Ws
Implemented in: PIC24F PIC24H PIC24E dsPIC30F dsPIC33F dsPIC33E
X X X X X X
Syntax: {label:} AND{.B} Wb, Ws, Wd
[Ws], [Wd]
[Ws++], [Wd++]
[Ws--], [Wd--]
[++Ws], [++Wd]
[--Ws], [--Wd]
Operands:
Wb [W0 ... W15]
Ws [W0 ... W15]
Wd [W0 ... W15]
Operation:
(Wb).AND.(Ws) Wd
Status Affected:
N, Z
Encoding: 0110 0www wBqq qddd dppp ssss
Description: Compute the logical AND operation of the contents of the source register
Ws and the contents of the base register Wb, and place the result in the
destination register Wd. Register direct addressing must be used for Wb.
Either register direct or indirect addressing may be used for Ws and Wd.
The ‘w’ bits select the address of the base register.
The ‘B’ bit selects byte or word operation (‘0’ for word, ‘1’ for byte).
The ‘q’ bits select the destination Address mode.
The ‘d’ bits select the destination register.
The ‘p’ bits select the source Address mode.
The ‘s’ bits select the source register.
Note: The extension .B in the instruction denotes a byte operation
rather than a word operation. You may use a .W extension to
denote a word operation, but it is not required.
Words: 1
Cycles:

Note 1:
In dsPIC33E and PIC24E devices, the listed cycle count does not apply to read and
read-modify-write operations on non-CPU Special Function Registers. For more
