eMIOS AND trgmux

[Ayaz]

Hi 

I want to test how fast we can trigger the ADC through emios, emios  to TRGMUX to  BCTU to ADC.

Firstly : 

I am trying to get an output from TRGMUX, which has the input from Emios_mcl to be triggered every 25 us.

1) Does Emios needs an interrupt controller handler (ISR)?

2) How to configure the input for trgmux?

TRGMUX_IP_INPUT_EMIOS0_RELOAD_OUT_CH0 or 

TRGMUX_IP_INPUT_EMIOS0_IPP_CH0

for getting the timing  form emios .

3) How to roue the pins for the TRGMUX_IP_SIUL2_0_3 on the reference manual?

Hi@Ayaz

eMIOS can directly trigger BCTU sampling, so you can ignore TRGMUX here.

please refer to this answer to calculate the time when eMIOS triggers BCTU sampling

Hi

Thanks for your response.

I want to test the capability for using Trgmux, so for now, I need to test the Emios and Trgmux. Based on the configuration above.

1) Does Emios need an interrupt controller handler (ISR)?

2) How to configure the input for Trgmux?

TRGMUX_IP_INPUT_EMIOS0_RELOAD_OUT_CH0 or 

TRGMUX_IP_INPUT_EMIOS0_IPP_CH0

for getting the trigger   form Emios .

3) How to roue the pins for the TRGMUX_IP_SIUL2_0_3 on the reference manual

Hi@Ayaz

1. Depending on your needs, you don’t need to do this at all.

2.TRGMUX_IP_INPUT_EMIOS0_RELOAD_OUT_CH0 or TRGMUX_IP_INPUT_EMIOS0_IPP_CH0 are both ok

3. I don’t understand why this port is used here,

TRGMUX_IP_INPUT_EMIOS0_RELOAD_OUT_CH0 (TRGMUX_IP_INPUT_EMIOS0_IPP_CH0 )->TRGMUX->BCTU_TRG23(47/71)

TRGMUX_IP_SIUL2_0_3
