Figure 2-2 Reset Timing
5.
For an external clock generator, RESET duration is measured during the time in which RESET is asserted,
V
CC
is valid, and the EXTAL input is active and valid.
For internal oscillator, RESET duration is measured during the time in which RESET is asserted and V
CC
is
valid. The specified timing reflects the crystal oscillator stabilization time after power-up. This number is
affected both by the specifications of the crystal and other components connected to the oscillator and
reflects worst case conditions.
When the V
CC
is valid, but the other “required RESET duration” conditions (as specified above) have not
been yet met, the device circuitry will be in an uninitialized state that can result in significant power
consumption and heat-up. Designs should minimize this state to the shortest possible duration.
