All output signals are powered by the digital supply (VCC).
Table 69 summarizes the states of the output signals during
the reset state (when VCC power exists in the reset state)
and during the Power Save mode.

The RESET and NMI input pins are active during the Power
Save mode. In order to guarantee that the Power Save cur-
rent not exceed 1 mA, these inputs must be driven to a volt-
age lower than 0.5V or higher than VCC - 0.5V. An input
voltage between 0.5V and (VCC - 0.5V) may result in power
consumption exceeding 1 mA.
