  • Page 6: Operation Modes And Functions

    TSC-25/RSA Series User’s Guide 4. Operation modes and functions 4-1. Outline TSC-20/IC enters the Initialization mode immediately after it is turned on or reset. In this mode, no setting is made and each mode shall be set. To transition to the available state, select the coordinate output rate and coordinate output mode and set the operation mode.
  • Page 7 TSC-25/RSA Series User’s Guide § STOP mode This mode is enabled only in the serial communication. This mode starts when in the idle mode, STOP mode start command is received. This mode stops ceramic vibrator’s vibration and enters the power saving mode where the operation stops.

  • Page 8: Initialization Mode And Idle Mode

    TSC-25/RSA Series User’s Guide 4-2. Initialization mode and idle mode After the power up or hardware reset, internal initialization setting is performed (about 500ms) and the transition to the initialization mode occurs, where waiting for the communication with host. In this mode, if external EEPROM is used, EEPROM data is read.

  • Page 17: Calibration Data Read Mode

    TSC-25/RSA Series User’s Guide 4-5. Calibration data read mode In this mode, data set in the calibration data setup mode is read from EEPROM, used to check the pa- rameter setting. This mode is executed from idle mode to transmit the stored calibration data, then the operation automati- cally transitions to idle mode.

  • Page 18: Calibration Data Mode

    TSC-25/RSA Series User’s Guide 4-6. Calibration data mode In this mode, based on calibration value obtained from the calibration data setup mode, coordinate value is corrected and output. In this mode, maximum output coordinate value can be limited. From the idle mode, this mode starts by receiving either command of coordinate data send start 1 – 3, and returns to the idle mode by receiving the calibration data send end command.
  • Page 19 TSC-25/RSA Series User’s Guide § Power-save mode “Coordinate data send start 1” command (0Ah) activates the transition to the coordinate data mode. If for 20 sampling times, no touch screen is input, ceramic vibrator’s vibration stops and the operation ends by entering the power saving mode.
