The output is equal to input I2 if input I1 is true and equal to input I3 if input I1 is
false.
I1 I2 I3 O
0 I2 I3 I3
1 I2 I3 I2
Input I1: Boolean value
Input I2 and I3: 24 bit integer values (23 bits + sign)
Output (O): 24 bit integer value (23 bits + sign)
Timing function
TOFF
I1
O
I2
The output is true when input I1 is true. The output is false when input I1 has been
false for a time equal or longer than input I2.
Input I1
1
0
Output
All bits 1
All bits 0
Values on display: True = -1, false = 0.
Input I1: Boolean value
Input I2: 24 bit integer value (23 bits + sign). One corresponds to 1 ms.
Output (O):
- 24 bit integer value (packed boolean)
