    This is a counting operation when DIR=1. If DIR=0 and the gate control signal (B-phase/DOWN) is HIGH, the counter counts down with the rising edge of a single-phase pulse (A-phase/UP). If DIR=0 and the gate control signal is LOW, the counter stops. CNT24-4(PCI)

  • Page 55: Digital Filter (Command Ch0:04H, Ch1:09H, Ch2:0Eh, Ch3:13H)

    Since external input signals (except the general input signal) are read into the internal counter through the digital filter, these signals are read after a four clock delay of the sampling frequency. With the default setting, external input signal is read with 400nsec delay. CNT24-4(PCI)

  • Page 56: Figure 4.11. Digital Filter

    - Some noise causes more than a four clock delay of the set frequency. - If the level changes faster than the sampling clock frequency that has been set, the level change is invalid and there is no count. Latch count. CNT24-4(PCI)

    Setting these bits "0," enables the interrupt. Notes! - In the default setting, all of the four channels and the timer are disabled (1Fh). - However, to mask a channel or the timer will not effect the function of setting/resetting the related status. CNT24-4(PCI)
