POWER-ON RESET OPERATION
An internal power-on reset (POR) is implemented on the
ADuC7128/ADuC7129. For LVDD below 2.45 V, the internal
POR holds the ADuC7128/ADuC7129 in reset. As LVDD rises
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, IOVDD, has reached a stable 3.0 V minimum
level by this time. On power-down, the internal POR holds the
ADuC7128/ADuC7129 in reset until LVDD has dropped below
2.45 V. Figure 72 illustrates the operation of the internal POR
in detail.
