Enables the watchdog timer.
This function enables the watchdog timer counter and interrupt.
Definition at line 136 of file watchdog.h.
Referenced by WatchdogIntEnable().
|
inlinestatic |
Clears the watchdog timer interrupt.
The watchdog timer interrupt source is cleared, so that it no longer asserts.
Definition at line 442 of file watchdog.h.
|
inlinestatic |
Enables the watchdog timer.
This function enables the watchdog timer by calling WatchdogEnable().
Definition at line 393 of file watchdog.h.
|
inlinestatic |
Registers an interrupt handler for the watchdog timer interrupt.
This function does the actual registering of the interrupt handler. This function also enables the global interrupt in the interrupt controller; the watchdog timer interrupt must be enabled via WatchdogIntEnable(). It is the interrupt handler's responsibility to clear the interrupt source via WatchdogIntClear().
pfnHandler | is a pointer to the function to be called when the watchdog timer interrupt occurs. |
Definition at line 335 of file watchdog.h.
|
inlinestatic |
Gets the current watchdog timer interrupt status.
This function returns the interrupt status for the watchdog timer module.
Definition at line 413 of file watchdog.h.
|
inlinestatic |
Sets the type of interrupt generated by the watchdog.
This function sets the type of interrupt that is generated if the watchdog timer expires.
When configured to generate an NMI, the watchdog interrupt must still be enabled with WatchdogIntEnable(), and it must still be cleared inside the NMI handler with WatchdogIntClear().
ui32Type | is the type of interrupt to generate.
|
Definition at line 469 of file watchdog.h.
|
inlinestatic |
Unregisters an interrupt handler for the watchdog timer interrupt.
This function does the actual unregistering of the interrupt handler. This function clears the handler to be called when a watchdog timer interrupt occurs. This function also masks off the interrupt in the interrupt controller so that the interrupt handler no longer is called.
Definition at line 368 of file watchdog.h.
|
inlinestatic |
Enables the watchdog timer lock mechanism.
This function locks out write access to the watchdog timer configuration registers.
Definition at line 195 of file watchdog.h.
|
inlinestatic |
Gets the state of the watchdog timer lock mechanism.
This function returns the lock state of the watchdog timer registers.
true
: Watchdog timer registers are locked.false
: Registers are not locked. Definition at line 235 of file watchdog.h.
|
inlinestatic |
Gets the watchdog timer reload value.
This function gets the value that is loaded into the watchdog timer when the count reaches zero for the first time.
Definition at line 285 of file watchdog.h.
|
inlinestatic |
Sets the watchdog timer reload value.
This function configures the value to load into the watchdog timer when the count reaches zero for the first time; if the watchdog timer is running when this function is called, then the value is immediately loaded into the watchdog timer counter. If the ui32LoadVal
parameter is 0, then an interrupt is immediately generated.
ui32LoadVal | is the load value for the watchdog timer. |
Definition at line 264 of file watchdog.h.
|
inlinestatic |
Disables the watchdog timer reset.
This function disables the capability of the watchdog timer to issue a reset to the processor after a second timeout condition.
Definition at line 178 of file watchdog.h.
|
inlinestatic |
Enables the watchdog timer reset.
This function enables the capability of the watchdog timer to issue a reset to the processor after a second timeout condition.
Definition at line 157 of file watchdog.h.
|
inlinestatic |
Determines if the watchdog timer is enabled.
This function checks to see if the watchdog timer is enabled.
true
: Watchdog timer is enabled.false
: Watchdog timer is disabled. Definition at line 114 of file watchdog.h.
|
inlinestatic |
Disables stalling of the watchdog timer during debug events.
This function disables the debug mode stall of the watchdog timer. By doing so, the watchdog timer continues to count regardless of the processor debug state.
Definition at line 512 of file watchdog.h.
|
inlinestatic |
Enables stalling of the watchdog timer during debug events.
This function allows the watchdog timer to stop counting when the processor is stopped by the debugger. By doing so, the watchdog is prevented from expiring and resetting the system (if reset is enabled). The watchdog instead expires after the appropriate number of processor cycles have been executed while debugging (or at the appropriate time after the processor has been restarted).
Definition at line 494 of file watchdog.h.
|
inlinestatic |
Disables the watchdog timer lock mechanism.
This function enables write access to the watchdog timer configuration registers.
Definition at line 215 of file watchdog.h.
|
inlinestatic |
Gets the current watchdog timer value.
This function reads the current value of the watchdog timer.
