3.3.2
The divide block supports signed and unsigned integer
divide operations with the following data sizes:
1.
2.
3.
4.
The quotient for all divide instructions ends up in W0
and the remainder in W1. 16-bit signed and unsigned
DIV instructions can specify any W register for both the
16-bit divisor (Wn), and any W register (aligned) pair
(W(m + 1):Wm) for the 32-bit dividend. The divide algo-
rithm takes one cycle per bit of divisor, so both
32-bit/16-bit and 16-bit/16-bit instructions take the
same number of cycles to execute.

INSTRUCTIONS THAT USE THE SINGLE BIT AND MULTI-BIT SHIFT OPERATION
Arithmetic shift right source register by one or more bits.
Shift left source register by one or more bits.
Logical shift right source register by one or more bits.
3.3.3
The PIC24F ALU supports both single bit and
single-cycle, multi-bit arithmetic and logic shifts.
Multi-bit shifts are implemented using a shifter block,
capable of performing up to a 15-bit arithmetic right
shift, or up to a 15-bit left shift, in a single cycle. All
multi-bit shift instructions only support Register Direct
Addressing for both the operand source and result
destination.
A full summary of instructions that use the shift
operation is provided in Table 3-2.
