Architecture
dsPIC33C/E/F, dsPIC30
Description
Returns the psv page number of the object whose address is given as a parameter. The
argument p
must be the address of an object in an EE data, PSV
or executable memory space; otherwise an error message is produced and the compilation
fails. See the space
attribute in 9.10 Variable Attributes.
Prototype
uint16_t __builtin_psvpage(const void *p);
Argument
p
– literal address of an object
Return Value
Returns the psv page number of the object whose address is given as a parameter.
Assembler Operator
psvpage
Error Messages
The following error message is produced when this function is used incorrectly:
“Argument to __builtin_psvpage()
is not the address of an object in
code, psv, or eedata section.”
The argument must be an explicit object address.
For example, if obj
is object in an executable or
read-only section, the following syntax is valid:
uint16_t page = __builtin_psvpage(&obj);
