Component
Init_PPI for HC08
Programmable Periodic Interrupt (PPI)
Device Initialization
(Description of the component parameters.)
- Device - Selection of the PPI device module.
-
Settings - Common PPI module settings.
-
Clock settings - Clock/timing settings of the module.
-
Clock source - The property sets clock source of module.
This item modifies the PPI1CLKS[0:1] bits in the PPI1SCR register. -
Prescaler - The property sets interrupt rate of module.
This item modifies the PPI1IE[0:2] bits in the PPI1SCR register. -
Interrupt timeout - Period of the interrupts generation (for information only).
This item is influenced by the following properties: Clock source, Prescaler.
-
Clock source - The property sets clock source of module.
-
Clock settings - Clock/timing settings of the module.
-
Pins - Module pins/signals settings.
-
External clock source - External clock source pin.
This item is influenced by the following properties: Clock source.
The following items are available only if the group is enabled (the value is "Enabled"):
- Source pin - Name of the pin used as external clock input.
-
External clock source - External clock source pin.
-
Interrupts - Interrupts settings of the module.
- Interrupt - Interrupt vector (for information only).
-
Programmable periodic interrupt - Enable/disable PPI interrupt.
This item modifies the PPI1MSK bit in the PPI1SCR register. -
ISR name - Name of the interrupt service routine (ISR) invoked by this interrupt vector.
The user code of the routine should handle all respective interrupt flags correctly.
