Registration of routines
A user registered routine is called when the user watchdog timer of the VxWorks part times out.
Use the C Controller module dedicated function (CCPU_EntryWDTInt) to register routines.
■Function list
Function name
CCPU_EntryWDTInt
For details on the C Controller module dedicated functions, refer to the following manual.
MELIPC MI5000 Series Programming Manual (VxWorks)
When the C Controller module dedicated function (CCPU_EntryWDTInt) is executed multiple times, the
registered routine of the C Controller module dedicated function (CCPU_EntryWDTInt) executed most
recently is enabled. (The registered routine is executed as an interrupt service routine (ISR).) Set the routine
to be registered to minimize the routine processing and keep the processing time as a short as possible.
Precautions
• The registered routine is not executed while the operating system is in the interrupt-disabled state on the VxWorks part.
• Registered routines can use only C Controller module dedicated functions for ISR. Do not use other functions. (An error
check of registered functions is not performed. )
