PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04
3.3 Special MCU Features
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 features a 17-bit by 17-
bit, single-cycle multiplier. The multiplier can perform
signed, unsigned and mixed-sign multiplication. Using
a 17-bit by 17-bit multiplier for 16-bit by 16-bit
multiplication makes mixed-sign multiplication
possible.
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices support 16/16
and 32/16 integer divide operations. 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 multi-bit data shifter is used to perform up to a 16-bit,
left or right shift in a single cycle.
