  • Page 29: Description Of Input Commands

    4. Using the I/O Address Map Description of Input Commands Reading a Count (command 00h - 07h) By reading the contents of the READ register for a corresponding channel, this command reads a count value. By issuing the command to the output port +16 and reading the input port +17 two times, you can read low, middle, and high count values.

    4. Using the I/O Address Map Status (command 12h) Command Function Data length Status 8-bit Indicates a carry-up occurred for the count on each channel. By issuing 12H to the output port +16 and reading the input port +17, you can monitor the status. The corresponding bit is set to "1"...

  • Page 31: Description Of Output Commands

    4. Using the I/O Address Map Description of Output Commands Initial Count Value (command 00h - 07h) The command is issued to the output port +16, and an initial count value is set on the output port +17. Because count data consists of 16 bits, count values are output two times in low, middle, and high order, 8 bits each time.

  • Page 32: Status Reset (Command 12H)

    4. Using the I/O Address Map Status Reset (command 12h) Command Function Data length Status Reset 8-bit The interrupt sense sets an applicable bit to "1" when carry-up condition is detected on a given channel. When the applicable bit is "1", an interrupt signal is not generated when another carry-up condition arises.

  • Page 33: Digital Filter (Command 15H)

    4. Using the I/O Address Map Digital Filter (command 15h) Using this function digitally filters the signals at all input pins by means of hardware. Use it to prevent input signal noise and chattering from being detected by mistake. The level is checked at each clock sampling time. If the signal level remains the same for longer than the time set for the digital filter, the signal is treated as a valid input and the level of the PC signal is changed.
  • Page 34 4. Using the I/O Address Map Set Digital Filter Time Output setting data "ST4 - ST0" to the "time setting" output port to set the digital filter time.
