DS70265E-page 20

The dsPIC33FJ12MC201/202 supports 16/16 and 32/

16 divide operations, both fractional and integer. All

divide instructions are iterative operations. They must

be executed within a REPEAT loop, resulting in a total

execution time of 19 instruction cycles. The divide

operation can be interrupted during any of those

19 cycles without loss of data.

A 40-bit barrel shifter is used to perform up to a 16-bit

left or right shift in a single cycle. The barrel shifter can

be used by both MCU and DSP instructions.
