int data2, unsigned int data3, unsigned int data4, void* func)

data1

Setup data 1

data2

Setup data 2

data3

Setup data 3

data4

func

Callback function pointer

(Specify 0 if no callback functions are set.)

Description

Sets a specified timer to pulse with 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_FC32 Selects

f

C32

for the count source.

RAPI_TIMER_ON

Sets the timer to start operating in

__CreatePulseWidthMeasurementMode.

RAPI_TIMER_OFF

Sets the timer to stop operating in

__CreatePulseWidthMeasurementMode.

• Specifiable definition values when timer B is used (RAPI_TIMER_B0 to

RAPI_TIMER_B2 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.

[data2]

Specify the interrupt priority level (0–7) to be set in the interrupt control register.

[data3]

Specify 0.
