TIC12400-Q1: MSDI ADC configuration

Part Number: TIC12400-Q1
Other Parts Discussed in Thread: TIC12400

Hello team,

I am planning to use TIC12400 in our BCM product , I have confusion configuring it as Analog input , Please look into my below questions and provide the solution.

Is it possible to configure all 24 inputs as ADC .?

What is the maximum Voltage can be applied to the input pin , if it is configured as ADC.?

Is it possible to wake up the MSDI by setting input as Analog threshold?

please consider it as a high priority.

    Yes.  Each input can be individually configured to use either the comparator or ADC in the Mode Register (0x32).

    The Recommended Maximum voltage for an Input Pin is specified as 35V with an Absolute Maximum of 40V.  However, the ADC only has a sampling range between 0V and 6V.  A voltage between 6V and 35V can safely be applied to the pin without causing damage to the ADC, but the ADC will return the maximum code of 1023 for any voltage greater than 6V.

    Yes.  The ADC threshold levels are configured in the THRES_CFG0 to THRES_CFG4 Registers (0x29 to 0x2D).  The threshold for that particular Input Channel to use can be mapped or assigned n the THRESMAP_CFG0 to THRESMAP_CFG2 Registers (0x2E to 0x30).  Note that not all thresholds are available to all Input channels and section 8.3.4 contains a table (8-1) that outlines which thresholds are available for the different channels.
