POWER-ON RESET OPERATION
An internal power-on reset (POR) is implemented on the
ADuC7128/ADuC7129. For LV
POR holds the ADuC7128/ADuC7129 in reset. As LV
above 2.45 V, an internal timer times out for typically 64 ms
before the part is released from reset. The user must ensure that
the power supply, IOV
level by this time. On power-down, the internal POR holds the
ADuC7128/ADuC7129 in reset until LV
2.45 V. Figure 72 illustrates the operation of the internal POR
in detail.
