C Language Features
A psect can be created in assembler code by using the PSECT assembler directive (see Section
4.3.8.3). In C, user-defined psects can be created by using the #pragma psect preprocessor di-
rective, see Section 3.12.3.3.
3.9.1 Compiler-generated Psects
The code generator places code and data into psects with standard names which are subsequently
positioned by the default linker options. These psects are described below.
powerup Which contains executable code for the standard or user-supplied power-up routine.
idata These psects contain the ROM image of any initialised variables. These psects are copied into
irdata These psects contain the ROM image of any initialised near variables. These psects are
ibigdata These psects contain the ROM image of initialised objects which at runtime reside in the
ifardata This psect contains the ROM image of initialised objects which at runtime reside in the
text Is a global psect used for executable code and library functions.
const These psects hold objects that are declared const and string literals which are not modifiable.
config Used to store the configuration words.
idloc Used to store the ID location words.
eeprom_data Used to store data to be programmed into the EEPROM data area.
intcode Is the psect which contains the executable code for the entry point to the default or high-
intcodelo Is the psect which contains the executable code the low-priority interrupt service routine.
The compiler-generated psects which are placed in ROM are:

the data psects at startup.
copied into the rdata psects at startup.
bigdata psect. This includes global or static local char objects or char arrays, and arrays
whose size exceeds the size of a RAM bank.
fardata psect.
priority interrupt service routine. This psect is linked to the interrupt vector at address 08H.
This psect is linked to the interrupt vector at address 018H.
