Psects
assembler code. The linker will group all data for a particular psect into a single segment.

not recommended), or write your own assembly language subroutines, you should read this section
carefully.
4.3.8.3). In C, user-defined psects can be created by using the #pragma psect preprocessor direc-
tive, see Section 3.12.3.5.
3.9.1 Compiler-generated Psects
The code generator places code and data into psects with standard names which are subsequent
positioned by the default linker options. These psects are described below.
clrtext Used by some startup routines for clearing the rbss_n psects.
checksum If a checksum has been requested, the result will be stored in this psect.
config Used to store the configuration word.
cstrings High-End processors use the cstrings psect to store const objects and string literals. ROM
eeprom_data Used to store data into EEPROM memory.
end_init Used by initialisation code which, for example, clears RAM.
float_textn Used by some library routines, and in particular by arithmetic routines.It is possible
idata_n These psects (where n is the bank number) contain the ROM image of any initialised vari-
idloc Used to store the ID location words.
init Used by initialisation code which, for example, clears RAM.
intcode Is the psect which contains the executable code for the interrupt service routine.
intentry Contains the entry code for the interrupt service routine. This code saves the necessary

If you are using PICC to invoke the linker, you don’t need to worry about the information doc-
A psect can be created in assembler code by using the PSECT assembler directive (see Section
The compiler-generated psects which are placed in the program space are:

a program.
