CCPU_EntryWDTInt

Registers a routine to be called when a user WDT error interrupt of the VxWorks part occurs.
Format
short CCPU_EntryWDTInt(short sType, CCPU_FUNCPTR pFuncPtr)
Argument
Argument Name
sType WDT type
*1
pFuncPtr Registered routine
*1 The data type is defined as a void type in the include file "CCPUFunc.h".
Description
• Registers a routine to be called when a user WDT error interrupt of the VxWorks part occurs.
• When this function is executed several times, the last registered routine will be in effect.
• The routine registered with this function is executed as an interrupt service routine (ISR) when a user WDT error occurs. (If
the CCPU_ResetWDT function is not executed within the time interval specified by this function, the WDT error will occur.) )
Precautions
• The registered routine is not executed while the operating system is in the interrupt-disabled state.
• For processing a routine to be registered in the registered routine (pFuncPtr), note the following:
A routine to be registered must not have an argument. (Do not pass an argument from an interrupt.)
When registering a routine, observe the considerations on the interrupt service routine (ISR).
Register minimal processing of a routine so that the processing time is as short as possible.
Only the C Controller module dedicated function (for ISR) can be used for a routine to be registered. Do not use any other
function. (An error of a function to be registered is not checked.)
Warning
If a routine that does not observe the considerations on interrupt service routine (ISR) is registered, the operating system will
be out of control.
Make sure to use the routine after carefully verifying the operation and performance.
