TCAN1145-Q1: Register settings for selective wake

Hello Experts,

My customer would like to check register settings for selective wake. Customer is now evaluating selective wake via attached register settings but he could not get wake function. Would you please check it?

    Hello Yasushi,

    There are a couple things that go into turning on selective wake on this device. Here is an application note that details the process. I looked through the excel sheet and it looks like in register 10h bit 7 and 5 are enabled however bit 5 is written as SWE_DIS. I'm unsure where this information came from since I looked through the data sheet and bit 5 is the Fault Detection enable bit. This feature does not seem available on the TCAN1145-Q1 and bits 5-3 should be reserved. Try setting this bit as 0.

    Best,

    Chris
