4.7.4 Preprocessor Macros

PIC16 port defines the following preprocessor macros while translating a source.

Macro | Description
__SDCC_pic16 | Port identification
pic18fxxxx | MCU Identification. xxxx is the microcontrol identification number, i.e. 452, 6620, etc
__18Fxxxx | MCU Identification (same as above)
STACK_MODEL_nnn | nnn = SMALL or LARGE respectively according to the stack model used

In addition the following macros are defined when calling assembler:

Macro | Description
__18Fxxxx | MCU Identification. xxxx is the microcontrol identification number, i.e. 452, 6620, etc
__SDCC_MODEL_nnn | nnn = SMALL or LARGE respectively according to the memory model used for SDCC
STACK_MODEL_nnn | nnn = SMALL or LARGE respectively according to the stack model used
