LDC1614: Config Register - Reserved Fields

Tim Goll

Part Number: LDC1614

Tool/software:

Hi there!

When playing around with your LDC Calculator Tool, the output suggests that the config in the register 0x1A should be set to 0x1600 (0b0001'0110'0000'0000). This directly contradicts with your datasheet which says that it should be set to 0b000001. There is no explanation on this value other that it being reserved. Since the datasheet explicitly says to set it to that specific value, I wonder if the value makes a difference.

Thanks.

    Tim,

    This is an older part, so the detailed background on the RESERVED register bits isn't readily available.
    In the tool, the (5:0) RESERVED bits in the CONFIG register don't appear in any calculations, so the lower six displayed CONFIG bits are don't-cares.

    Regards,
    John
