3 DETAILS OF FUNCTION
3.1 C Intelligent Function Module Dedicated Functions
CITL_WaitSwitchEvent
This function waits for a switch interrupt event of a C intelligent function module to occur.
■ Format
short CITL_WaitSwitchEvent(short sSwitch, unsigned long ulTimeout)
■ Argument
■ Description
• This function waits for a switch interrupt event specified to the switch interrupt event type (sSwitch).
• If an interrupt event has already been notified at the time when this function is called, this function returns immediately.
• If the same switch interrupt event has been notified several times at the time of calling the CITL_WaitSwitchEvent function,
it is treated as a single switch interrupt event.
• The specified timeout value is rounded to the tick unit. Specify a timeout value of one tick or more.
For the MODE switch interrupt event, an event issuance status cannot be judged from the appearance. To check the issued
status of MODE switch interrupt event, implement the processing such as receiving a switch interrupt event using the
CITL_WaitSwitchEvent function and making the USER LED turn ON.
