The PIC24HJ12GP201/202 CPU module has a 16-bit
(data) modified Harvard architecture with an enhanced
instruction set and addressing modes. The CPU has a
24-bit instruction word with a variable length opcode
field. The Program Counter (PC) is 23 bits wide and
addresses up to 4M by 24 bits of user program memory
space. The actual amount of program memory
implemented
instruction prefetch mechanism is used to help
maintain
execution. All instructions execute in a single cycle,
with the exception of instructions that change the
program
instruction and the table instructions. Overhead-free,
single-cycle program loop constructs are supported
using the REPEAT instruction, which is interruptible at
any point.
The PIC24HJ12GP201/202 devices have sixteen, 16-bit
working registers in the programmer’s model. Each of the
working registers can serve as a data, address or
address offset register. The 16th working register (W15)
operates as a software Stack Pointer (SP) for interrupts
and calls.
The PIC24HJ12GP201/202 instruction set includes
many addressing modes and is designed for optimum

executing a data (or program data) memory read, a
working register (data) read, a data memory write, and
a program (instruction) memory read per instruction
cycle. As a result, three parameter instructions can be
supported, allowing A + B = C operations to be
executed in a single cycle.

3.1
The data space can be linearly addressed as 32K words
or 64 Kbytes using an Address Generation Unit (AGU).
The upper 32 Kbytes of the data space memory map can
optionally be mapped into program space at any 16K
program word boundary defined by the 8-bit Program
Space Visibility Page (PSVPAG) register. The program to
data space mapping feature lets any instruction access
program space as if it were data space.
The data space also includes 2 Kbytes of DMA RAM,
which is primarily used for DMA data transfers, but may
be used as general purpose RAM.

The PIC24HJ12GP201/202 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
possible.
The PIC24HJ12GP201/202 supports 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.
