C Language Features
text Is a global psect used for executable code for some library functions.
textn These psects (where n is a number) contain all executable code for the Midrange processors.
The compiler-generated psects which are placed in the data space are:
intsave Holds the W register saved by the interrupt service routine. If necessary, the W register will
intsave_n May also hold the W register saved by the interrupt service routine. (See the description
nvbit_n These psects are used to store persistent bit variables. They are not cleared or otherwise
nvram_n These psects are used to store persistent variables. They are not cleared or otherwise
rbit_n These psects are used to store all bit variables except those declared at absolute locations.
rbss_n These psects contain any uninitialized variables.
rdata_n These psects contain any initialised variables.
fnauton These psects contain the auto and parameter variables for the entire program. n is a number
3.9 Interrupt Handling in C
The compiler incorporates features allowing interrupts to be handled from C code. Interrupt func-
tions are often called interrupt service routines (ISR). Interrupts are also known as exceptions.
3.9.1 Interrupt Functions
The function qualifier interrupt may be applied to any number of C function definitions to allow
them to be called directly from the hardware interrupts. The compiler will process the interrupt
function differently to any other functions, generating code to save and restore any registers used
and exit using the appropriate instruction.
If the PICC option --STRICT is used, the interrupt keyword becomes __interrupt.
They also contains any executable code after the first goto instruction which can never be
skipped for the Baseline processors.
