Omron CK3W-GC 00 Series - Input Filter

Note that the conversion timing of AIN0, AIN1, AIN4, AIN5 and that of AIN2, AIN3, AIN6, AIN7 are not
the same.
To capture analog input data correctly
, the following register settings are required.
These register settings are the default.
Gate3[i].AdcAmpClockDiv = 5 or 4 (5 by default)
Gate3[i].AdcAmpCtrl = $FFFFFC01
Gate3[i].AdcAmpDelay = 0
Gate3[i].AdcAmpHeaderBits = 1
Gate3[i].AdcAmpStrobe = $FFFFFC
Gate3[i].AdcAmpUtoS = 0
Gate3[i].GpioCtrl = $00000000
Gate3[i].GpioDir[0] = $0000FFFF
Gate3[i].GpioPol[0] = $00000000

Input Filter
The Analog Input Unit incorporates a hardware filter.
Y
ou can select the filter cut-of
f frequency from among 24.5 kHz, 12.2 kHz, 4.3 kHz, and 3.2 kHz and
switch the frequency among them by setting the Gate3[i].GpioData[0] register as shown below.
