Properties:
(Properties are parameters of the component. Please see the Embedded Components page for more information.)
- Component name - Name of the component.
- Device - Selection of the PWU device module.
- Compare device - Compare device of the PWU module.
-
Settings - Common PWU module settings.
-
Clock settings - Clock/timing settings of the module.
-
Clock source - Select the clock source for the prescaler.
This item modifies the PWUCLKSEL bit in the PWUSC register.
There are 2 options:
- BUSCLK x 4: BUSCLK x 4 is selected as the clock source for the prescaler.
- 32 kHz RC oscillator: The internal 32 kHz RC oscillator is selected as the clock source for the prescaler.
-
Prescaler - Select one of the sixteen prescaler outputs to be the input to the PWU counter.
This item modifies the PS[3:0] bits in the PWUP register. -
Preset value - Preset value represents the modulo value for the counter. This value and the selected prescaler determine the frequency of the periodic interrupt.
This item modifies the PWUMOD register. -
Interrupt frequency - Frequency of the periodic interrupt (for information only).
Frequency is calculated using the formula:
Frequency = (Clock source frequency / Prescaler) * Preset value
This item is influenced by the following properties: Clock source, Prescaler, Preset value.
-
Clock source - Select the clock source for the prescaler.
-
Enabled in Stop Mode - Select yes to allow the PWU module to continue running in stop mode.
This item modifies the SMODE bit in the PWUSC register.
-
Clock settings - Clock/timing settings of the module.
-
Interrupts - Interrupts settings of the module.
-
Periodic Wakeup - Periodic Wakeup interrupt settings.
- Interrupt - Interrupt vector (for information only).
-
Periodic Wakeup - Enable/disable Periodic Wakeup interrupt.
This item modifies the PWUIE bit in the PWUSC 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. The routine must be implemented in the user code, it is not generated by Processor Expert. Find external prototypes of the ISRs in the component module header file.
-
Periodic Wakeup - Periodic Wakeup interrupt settings.
-
Initialization - Initialization options of the module.
- Call Init method - The Init method of the component may be called after power-on or reset (in initialization code) by PE. yes - The Init method is called by PE. no - The Init method is not called by PE, it should be called in user's code.
-
PWU module - Enable/disable the periodic wakeup module.
This item modifies the PWUON bit in the PWUSC register.
