POWER-ON RESET OPERATION
An internal power-on reset (POR) is implemented on the
ADuC7023. For LV

timer times out for typically 64 ms before the part is released
from reset. The user must ensure that the power supply IOV
has reached a stable 2.7 V minimum level by this time. Likewise, on
power-down, the internal POR holds the part in reset until
LV
Figure 53 illustrates the operation of the internal POR in detail.
