__CreatePulsePeriodMeasurementMode
Synopsis
Boolean __CreatePulsePeriodMeasurementMode(unsigned long data1,
unsigned int data2, unsigned int data3, unsigned int data4, void* func)
data1 Setup data 1
data2 Setup data 2
data3 Setup data 3
data4 Setup data 4
func Callback function pointer
(Specify 0 if no callback functions are set.)
Description Sets a specified timer to pulse period measurement mode.
[data1]
For data1, the following definition values can be set. To set multiple definition values
at the same time, use the symbol “|” to separate each specified value.
RAPI_TIMER_B0 Uses timer B channel 0.
RAPI_TIMER_B1 Uses timer B channel 1.
RAPI_TIMER_B2 Uses timer B channel 2.
RAPI_TIMER_B3 Uses timer B channel 3.
RAPI_TIMER_B4 Uses timer B channel 4.
RAPI_TIMER_B5 Uses timer B channel 5.
RAPI_F1 Selects f
1
for the count source.
RAPI_F2 Selects f
2
for the count source.
RAPI_F8 Selects f
8
for the count source.
RAPI_F32 Selects f
32
for the count source.
RAPI_FC32 Selects f
C32
for the count source.
RAPI_TIMER_ON Sets the timer to start operating in __CreatePulsePeriodMeasurementMode.
RAPI_TIMER_OFF Sets the timer to stop operating in __CreatePulsePeriodMeasurementMode.
RAPI_RISING_
RISING
Selects measurement of an interval from the rise to the next rise of a
measurement pulse.
RAPI_FALLING_
FALLING
Selects measurement of an interval from the fall to the next fall of a
measurement pulse.
• Specifiable definition values when timer B is used (RAPI_TIMER_B0 to
RAPI_TIMER_B5 specified)
(Count source) Specify one from { RAPI_F1, RAPI_F2, RAPI_F8, RAPI_F32,
RAPI_FC32 }. The default value is RAPI_F2.
(Operating
states set)
Specify one from { RAPI_TIMER_ON, RAPI_TIMER_OFF }. The default
value is RAPI_TIMER_OFF.
(Measurement
pulse)
Specify one from { RAPI_RISING_RISING, RAPI_FALLING_FALLING }.
The default value is RAPI_FALLING_FALLING.
[data2]
Specify the interrupt priority level (0–7) to be set in the interrupt control register.
