General Address acquire command

Other Parts Discussed in Thread: TMP112

Hello community,

the datasheet for the temperature sensor TMP112 says the following:

"The TMP112 does not support the General Address acquire command."

What does the aquire command mean?

Greetings

Joerg

    It should probably read "General Call Address Acquire"  which would be an address acquire command sent to all slaves on the bus via the general call address.

    From the TMP112 datasheet:

    GENERAL CALL
    The TMP112 responds to a two-wire General Call
    address (0000000) if the eighth bit is '0'. The device
    acknowledges the General Call address and
    responds to commands in the second byte. If the
    second byte is 00000110, the TMP112 internal
    registers are reset to power-up values. The TMP112
    does not support the General Address acquire
    command.
