MPC5744P does not work properly for PWM input capture based on MBD

[Yunhe]

Hi, 

When I configured input capture based on MBD to measure the frequency and duty cycle of PWM, I encountered a problem:
First of all, I configured one input capture according to the official example, as follows:

The code generated by this model is working properly，Then I continued to configure a few others, but found that they did not work properly, the configuration is as follows：

Through debug, it was found that this inoperable code did not generate a configured interrupt, that is, Input Capture 2 Flag Interrupt, and the corresponding interrupt function is as follows:

Of course, I have set the corresponding interrupt in the model and made sure that the PWM signal is input to the chip, as follows：

Later, normal operation can be realized through the register, and the corresponding configuration is as follows:

void ETimer_EtcInit(u8 ucETimerNo, u8 ucChNo)
{
	pETIMER[ucETimerNo]->ENBL.R &= (~((1<<ucChNo)));// disable Timer channels
	/* CTRL1---0x3F00
	 * bit15-13:	CNTMODE = 1	count rising edge of primary source
	 * bit12-8:	PRIsrc=0x1F	ip bus clock divide by 128
	 * bit12-8:	PRIsrc=0x1C	ip bus clock divide by 16
	 * bit7:	ONCE	= 0	count repeatedly
	 * bit6:	LENGTH	= 0	continue counting to roll over
	 * bit5:	DIR	= 0	count up
	 * bit4-0:	SECsrc=n	counter #n input pin
	 */
#if (PWM_FRE_RANGE == RANGE_HIGH)
	pETIMER[ucETimerNo]->CH[ucChNo].CTRL1.R = 0x3C00 | (ucChNo);
#else
	pETIMER[ucETimerNo]->CH[ucChNo].CTRL1.R = 0x3F00 | (ucChNo);
#endif
	pETIMER[ucETimerNo]->CH[ucChNo].COMP1.R = 0xFFFF;
	/* CCCTRL---0x0264
	 * bit15-13:	CLC2	= 0	never preload
	 * bit12-10:	CLC1	= 0	never preload
	 * bit9-8:	CMPMODE	= 2	comp1 for counting up;	comp2 for counting down
	 * bit7-6:	CPT2MODE= 1	CAPT2	capture falling edge
	 * bit5-4:	CPT1MODE= 2	CAPT1	capture rising edge
	 * bit3-2:	CFWM	= 1	capture FIFO water mark
	 * bit1:	ONESHOT	= 0	free running(not one shot mode)
	 * bit0:	ARM	= 0	input capture disable
	 */
	pETIMER[ucETimerNo]->CH[ucChNo].CCCTRL.R = 0x0264;
	/* INTDMA---0x0080
	 * bit15:	ICF2DE	= 0	Input Capture 2 Flag DMA disable

	 * bit4:	IELFIE	= 0	Input Edge Low Flag Interrupt  disable
	 * bit3:	TOFIE	= 0	Timer Overflow Flag Interrupt  enable
	 * bit2:	TCF2IE	= 0	Timer Compare 2 Flag Interrupt  disable
	 * bit1:	TCF1IE	= 0	Timer Compare 1 Flag Interrupt  disable
	 * bit0:	TCFIE	= 0	Timer Compare Flag Interrupt  disable
	 */
	pETIMER[ucETimerNo]->CH[ucChNo].INTDMA.R = 0x0080;		//Input Capture 2
	pETIMER[ucETimerNo]->CH[ucChNo].CTRL3.R	= 1;

	pETIMER[ucETimerNo]->ENBL.R |= (1<<ucChNo);				// enable Timer channels

	pETIMER[ucETimerNo]->CH[ucChNo].CCCTRL.B.ARM = 1;// input capture enable
}

Finally, after configuring the model according to the corresponding register, the code generated by the model still does not work properly。

I put all the models in the attachment:
The first model is a model that can work normally, and the second is a model that does not work properly。

Kind regards,
