Hello:
From CYT2Bx data sheet there is a section for Triggers multiplexer (Group0) where an input is defined as HSIOM: HSIOM_IO _INPUT[0:31].
Questions:
1- ¿How this input is related to PINs inputs?
2- ¿Where I can this information for specific derivative of CYT2Bx?
Thank You

Hi,
the inputs to the TRIGMUX are named TRIG_IN and the TRIGMUX outputs are named TRIG_DBG in the Alternate Function Pin Assignments chapter. See example below:

Hi @RBLx77 ,
Q: How this input is related to PINs inputs?
>The High Speed IO Mux (HSIOM) selects the hardware peripheral connection to an IO pin.
Pin specific connections for the 'DS_x'(DeepSleep Mapping) and 'ACT_x' (Active Mapping) settings are listed in the pinout section of the device datasheet.
> "The HSIOM_PRTx_PORT_SEL" registers allow a single selection from up to 32 different connections to each pin as listed in HSIOM connections reference table from device datasheet.
> Package pin list and alternate function section in datasheet defines pins alternative function in different power modes 'DS_x'(DeepSleep Mapping) and 'ACT_x' (Active Mapping)
## Please go through the following example for better understanding.
You consider selected peripheral connection Pin (P0.2) for CYT2B9 device can be configured by selecting the appropriate HCon#xx values for specific alternative functionality mentioned in datasheet.
For example
1> HCon#0: GPIO
2> HCon#8: PWM0_14
3> HCon#9: PWM0_17_N
4> HCon#10: TC0_14_TR0
5> HCon#11: TC0_17_TR1
6> HCon#14 :SCB0_SCL (0)
7> HCon#17: SCB0_RTS (0)
8> HCon#20: LIN1_EN
9> HCon#21: CAN0_1_TX
10> HCon#30 : SCB0_CLK (0)
- The Functionalities changes device by device and pin by pin Please go through the Notes present below the Alternate Pin function table.
Q Where I can this information for specific derivative of CYT2Bx?
- Please refer the device specific datasheet
>Table for HSIOM connections reference
>Table for Package pin list and alternate functions Section
- Please refer the device specific Register TRM
>For HSIOM_PRTx_PORT_SEL details
Thanks,

Hi @Shubham_D :
Thank you for your explanation, but my question it was related to
HSIOM_IO _INPUT[0:31] not to HSIOM_PRTx_PORT_SEL
as HSIOM_IO _INPUT[0:31] is mentioned in section "Trigger Group Inputs"
Specifically let say for Group 0 --> 39:54, to select one of the 15 inputs,
For this reason, my question was/is:
1-¿How HSIOM_IO _INPUT[0:31] are related to specific Port-Pins?
For example if HSIOM_IO _INPUT[x] is selected,
2-¿To which Port-Pin correspond to?
