All byte loads into any W register are loaded into the
LSB. The MSB is not modified.
A sign-extend (SE) instruction is provided to allow
users to translate 8-bit signed data to 16-bit signed
values. Alternatively, for 16-bit unsigned data, users
can clear the MSB of any W register by executing a
zero-extend (ZE) instruction on the appropriate
address.
Although most instructions are capable of operating on
word or byte data sizes, it should be noted that some
instructions, including the DSP instructions, operate
only on words.
3.2.5
An 8 Kbyte ‘near’ data space is reserved in X address
memory space between 0x0000 and 0x1FFF, which is
directly addressable via a 13-bit absolute address field
within all memory direct instructions. The remaining X
address space and all of the Y address space is
addressable indirectly. Additionally, the whole of X data
space is addressable using MOV instructions, which
support memory direct addressing with a 16-bit
address field.
3.2.6
The dsPIC DSC device contains a software stack. W15
is used as the Stack Pointer.
The Stack Pointer always points to the first available
free word and grows from lower addresses towards
higher addresses. It pre-decrements for stack pops and
post-increments for stack pushes, as shown in
Figure 3-9. Note that for a PC push during any CALL
instruction, the MSB of the PC is zero-extended before
the push, ensuring that the MSB is always clear.
There is a Stack Pointer Limit register (SPLIM)
associated
uninitialized at Reset. As is the case for the Stack
Pointer, SPLIM<0> is forced to ‘0’, because all stack
operations must be word-aligned. Whenever an
Effective Address (EA) is generated using W15 as a
source or destination pointer, the address thus
generated is compared with the value in SPLIM. If the
contents of the Stack Pointer (W15) and the SPLIM reg-
ister are equal and a push operation is performed, a
stack error trap will not occur. The stack error trap will
occur on a subsequent push operation. Thus, for
example, if it is desirable to cause a stack error trap
when the stack grows beyond address 0x2000 in RAM,
initialize the SPLIM with the value, 0x1FFE.

dsPIC30F6010A/6015
Similarly, a Stack Pointer underflow (stack error) trap is
generated when the Stack Pointer address is found to
be less than 0x0800, thus preventing the stack from
interfering with the Special Function Register (SFR)
space.
A write to the SPLIM register should not be immediately
followed by an indirect read operation using W15.

The dsPIC30F6010A/6015 devices support Data RAM
protection features which enable segments of RAM to
be protected when used in conjunction with Boot and
Secure Code Segment Security. BSRAM (Secure RAM
segment for BS) is accessible only from the Boot
Segment Flash code when enabled. SSRAM (Secure
RAM segment for RAM) is accessible only from the
Secure Segment Flash code when enabled.
See Table 3-3 for an overview of the BSRAM and
SSRAM SFRs.
