POWER-UP RESET
The MACH devices have been designed with the capa-
bility to reset during system power-up. Following
power-up, all flip-flops will be reset to LOW. The output
state will depend on the logic polarity. This feature pro-
vides extra flexibility to the designer and is especially
valuable in simplifying state machine initialization. A
timing diagram and parameter table are shown below.
Due to the synchronous operation of the power-up
reset and the wide range of ways V
CC
can rise to its
steady state, two conditions are required to insure a
valid power-up reset. These conditions are:
1. The V
CC
rise must be monotonic.
2. Following reset, the clock input must not be driven
from LOW to HIGH until all applicable input and
feedback setup times are met.
