    Hello Shamnad,

    Thanks for posting to the sensors forum!

    Have you connected a scope or a logic analyzer to the MSP430FR2355 outputs to confirm f you are seeing any data coming out of the microcontroller?

    Hi Isaac,

    Thanks for the reply

    Yes i have.

    Here is the screenshot while i am trying to read 0x0f  register of TMAG5170  to check CRC status..Looks like "ERR_STS" bit of of reply data is HIGH.

    What could be the reason.?

    . reading 0x0f register

    Hello Shamnad,

    Thanks for the information. Have you tried reading any of the status registers to check to see what the error could be attributed to?

    This is the only way to tell what the error could be the ERROR_STAT just reports that one of the error bit states is high. Try reading the AFE_STATUS (0x0D) or the SYS_STATUS (0x0E) registers to see if there are any issues reported within those registers.
