REGISTER 3-2:
3.3
The PIC24F ALU is 16 bits wide and is capable of addi-
tion, subtraction, bit shifts and logic operations. Unless
otherwise mentioned, arithmetic operations are 2’s
complement in nature. Depending on the operation, the
ALU may affect the values of the Carry (C), Zero (Z),
Negative (N), Overflow (OV) and Digit Carry (DC)
Status bits in the SR register. The C and DC Status bits
operate as Borrow and Digit Borrow bits, respectively,
for subtraction operations.
The ALU can perform 8-bit or 16-bit operations,
depending on the mode of the instruction that is used.
Data for the ALU operation can come from the W
register array, or data memory, depending on the
addressing mode of the instruction. Likewise, output
data from the ALU can be written to the W register array
or a data memory location.

Arithmetic Logic Unit (ALU)
The IPL3 bit is concatenated with the IPL<2:0> bits (SR<7:5>) to form the CPU interrupt priority level; see
Register 3-1 for bit description.
Unimplemented: Read as ‘0’
IPL3: CPU Interrupt Priority Level Status bit
1 = CPU interrupt priority level is greater than 7
0 = CPU interrupt priority level is 7 or less
Reserved: Read as ‘1’
Unimplemented: Read as ‘0’

The PIC24F CPU incorporates hardware support for
both multiplication and division. This includes a
dedicated hardware multiplier and support hardware
for 16-bit divisor division.
3.3.1
The ALU contains a high-speed, 17-bit x 17-bit
multiplier. It supports unsigned, signed or mixed sign
operation in several multiplication modes:
