0 = measurement range 1
Values
0 = non-inverted input signal – rising edge
1 = inverted input signal – falling edge
0 = non-inverted input signal – rising edge
1 = inverted input signal – falling edge
0 = non-inverted input signal – rising edge
1 = inverted input signal – falling edge
1 = measurement range 2
0 = auto-calibration after measurement
1 = auto-calibration disabled
0 = calibration off (only MR 1)
1 = calibration on
0 = use 32,768 kHz as cycle clock
1 = use 128 * CLKHS as period for cycle clock
(32µs with 4 MHZ high speed clock signal )
