2.5.15 Manifest Macros
The CCI defines the general form for macros that manifest the compiler and target
device characteristics. These macros can be used to conditionally compile alternate
source code based on the compiler or the target device.
The macros and macro families are details in Table 2-1.
2.5.15.1 EXAMPLE
The following shows code which is conditionally compiled dependent on the device
having EEPROM memory.
#ifdef __XC16__
void __interrupt(__auto_psv__) myIsr(void)
#else
void __interrupt(low_priority) myIsr(void)
#endif
2.5.15.2 DIFFERENCES
Some of these CCI macros are new (for example __CCI__), and others have different
names to previous symbols with identical meaning (for example __18F452 is now
__18F452__).
2.5.15.3 MIGRATION TO THE CCI
Any code which uses compiler-defined macros will need review. Old macros will con-
tinue to work as expected, but they are not compliant with the CCI.
2.5.15.4 CAVEATS
None.
TABLE 2-1: MANIFEST MACROS DEFINED BY THE CCI
Name Meaning if defined Example
__XC__ Compiled with an MPLAB XC compiler __XC__
__CCI__ Compiler is CCI compliant and CCI enforce-
ment is enabled
__CCI__
__XC##__ The specific XC compiler used (## can be 8,
16 or 32)
__XC8__
__DEVICEFAMILY__ The family of the selected target device __dsPIC30F__
__DEVICENAME__ The selected target device name __18F452__
