Power-up Reset

ATF750C(L)
The registers in the ATF750C(L)s are designed to reset during power-up. At a point
delayed slightly from V
output state will depend on the polarity of the output buffer.
This feature is critical for state machine initialization. However, due to the asynchronous
nature of reset and the uncertainty of how V
conditions are required:
1. The V
2. After reset occurs, all input and feedback setup times must be met before driving
3. The clock pin, or signals from which clock terms are derived, must remain stable
