Hello @procolo
I am sorry to post my question in this post. Because I already tried to post my question to ''Q&A" group but it didnt work.
Can you check my question?
I tried to configure eTimer_0 ETC_4 as a source FAULT_0 for eTimer 3. The PA[13] is assigned as an external input fault source. My configuration code is below:
void etimer_config ()
{
ETIMER_0.CH[4].CNTR.R = 1000;
ETIMER_0.CH[4].CTRL1.B.CNTMODE = 0x6U; /* Edge of secondary source triggers primary count till compare */
ETIMER_0.CH[4].CTRL1.B.PRISRC = 0x18U; /* primary count source = IP bus clock/2 */
ETIMER_0.CH[4].CTRL1.B.SECSRC = 0x4U; /* Counter #4 input pin etimer0.ch[4]/ PA[13] */
ETIMER_0.CH[4].CTRL1.B.ONCE = 0U; /* count repeatedly */
ETIMER_0.CH[4].CTRL1.B.LENGTH = 0U; /* count until rolling over */
ETIMER_0.CH[4].CTRL1.B.DIR = 0U; /* count up */
ETIMER_0.CH[4].CTRL2.B.OEN = 0U; /* output disable */
ETIMER_0.CH[4].CTRL2.B.RDNT = 0U; /* disable redundant channel */
ETIMER_0.CH[4].CTRL2.B.INPUT = 0x1U; /* External input signal enable*/
ETIMER_0.CH[4].CTRL2.B.SIPS = 0x1; /* Positive edge for recounting*/
ETIMER_0.CH[4].CTRL3.B.FMODE = 1; /* change mode */
ETIMER_0.CH[4].CTRL3.B.FDIS = 1; /* The channel OFLAG output is affected by this FAULT pin. */
ETIMER_0.CH[4].FILT.B.FILT_CNT = 7; /* sample filter counter*/
ETIMER_0.CH[4].FILT.B.FILT_PER = 255; /* input filter period */
ETIMER_0.CH[4].CCCTRL.B.CPT2MODE = 0x2U; /*Capture 2 Mode Control*/
ETIMER_0.CH[4].CCCTRL.B.CPT1MODE = 0x2U; /*Capture 1 Mode Control*/
ETIMER_0.CH[4].CCCTRL.B.CFWM = 0x1U; /*FIFO = 2*/
}
void FAULT_PIN_Configure ()
{
SIUL2.MSCR_MUX[206].R = 0x1U;
}
When this program operates, the PWM of eTimer_3 already disable, but it is enable when the fault pin PA[13] change the state. Can you review my configuration?
