TCAN4550-Q1: SDO data signal.

Part Number: TCAN4550-Q1


Hi team,

I'd like to know about the output of SDOpin.

A voltage drop occurs momentarily at the rising and falling edges of the signal.
Could you give me some advice on why this happens?




Sincerely.
Kengo.

    Kengo,

    It looks like there are two different sources driving this pin, as if the TCAN4550-Q1 is driving it at first and then let's go and MCU begins driving it. However, that doesn't make any sense. Does this happen every single time there is a SPI transcaction?

    Regards,
