  • Page 18: Using The I/O Address Map

    Using the I/O Address Map 4. Using the I/O Address Map Starting I/O Address When connected to a CPU-SBxx(FIT)GY, the ADI12-8(FIT)GY can directly receive I/O commands from the controller module. Depending on how the Device ID is set, the I/O addresses indicated below will be used exclusively by the ADI12-8(FIT)GY. Because the address bus on which the I/O address space is specified is not fully decoded in continued 16 bits, four starting I/O addresses exist in each Device ID.

  • Page 24: Overview Of The Sampling Function

    Using the I/O Address Map Overview of the Sampling Function When a start-sampling command is issued, analog input signals are converted into 12-bit digital data at a maximum rate of 10μsec/ch + 20μsec under pre-set sampling conditions. Two sampling modes are supported: - Software mode: Stores data from a channel specified by a data-fetch command into an internal read buffer.
  • Page 25 Using the I/O Address Map The sampling operation can be checked by monitoring the Start status. Initialize An interrupt can also be generated as the status changes.
