Component RTIshared
Real Time Interrupt Shareable
Component Level: High
Category: CPU Internal Peripherals-Timer
Properties:
(Properties are parameters of the component. Please see the Embedded Components page for more information.)
  • Component name - Name of the component.
  • Periodic interrupt source - Periodic interrupt source: compare register, reload register, free running counter, time base counter function, RTI (the roll down menu propose the possible timers).
    Compare and reload registers generate interrupt on matching their value with the counter, free-running generates interrupt on the counter overflow. RTI and time base module generate a periodic interrupt by dividing the crystal or system clock frequency.
  • Counter - Name of the counter used by this component (for information only).
  • Interrupt service/event - Component requires the interrupt service for the timer function. The component functionality depends on the interrupt service and will not operate if the CPU interrupts are disabled. For details please refer to chapter "interrupt service in the component's generated code".
    The following items are available only if the group is enabled (the value is "Enabled"):
    • Interrupt - Interrupt vector invoked from the timer (for information only).
    • Interrupt priority - Priority of the interrupt associated with the timer.
  • Resolution - Resolution and precision of a time and date. It is necessary to type here both value and unit (see Timing Setting Syntax). The setting may be made with the help of the Timing dialog box that gets open when clicking on button (...).
  • Same resolution in modes - Resolution is exactly the same in all speed modes (high, low, slow). If you select 'Yes' timing will keep with tolerance 1 tick. If you select 'No' timing will keep with setting precision only.
  • Component uses entire timer - The component can use every subsystem of the timer, more actions may be done by HW instead of SW but no other component can share the timer.
  • CPU clock/speed selection - Settings for the CPU speed modes: if the component is supported or not.
    For details about speed modes please refer to page Speed Modes Support.
