CCS C Compiler Manual PCB / PCM / PCH

INT_OSC_FAIL or INT_OSCF Interrupt fires when the system oscillator fails and the processor
switches to the internal oscillator.
Relevant Include Files:
None, all functions built-in
Relevant getenv()
parameters:
None
Example Code:
For PIC18F8722
setup_oscillator(OSC_32MHZ); //sets the internal oscillator to 32MHz (PLL enabled)
If the internal oscillator fuse option are specified in the #fuses and a valid clock is specified in
the #use delay(clock=xxx) directive the compiler automatically sets up the oscillator. The #use
delay statements should be used to tell the compiler about the oscillator speed.
Interrupts
The following functions allow for the control of the interrupt subsystem of the microcontroller.
With these functions, interrupts can be enabled, disabled, and cleared. With the preprocessor
directives, a default function can be called for any interrupt that does not have an associated
ISR, and a global function can replace the compiler generated interrupt dispatcher.
Relevant Functions:
disable_interrupts()
enable_interrupts()
ext_int_edge()
clear_interrupt()
interrupt_active()
interrupt_enabled()
Relevant Preprocessor:
#DEVICE HIGH_INTS=
#INT_XXX fast
Disables the specified interrupt.
Enables the specified interrupt.
Enables the edge on which the edge interrupt should trigger. This
can be either rising or falling edge.
This function will clear the specified interrupt flag. This can be
used if a global isr is used, or to prevent an interrupt from being
serviced.
This function checks the interrupt flag of specified interrupt and
returns true if flag is set.
This function checks the interrupt enable flag of the specified
interrupt and returns TRUE if set.
This directive tells the compiler to generate code for high priority
interrupts.
This directive tells the compiler that the specified interrupt should
