Refer to
Table 25
for additional PLL specifications.

Refer to
Table 3
for pins with internal pull-up devices.
3
This parameter is characterized before qualification rather than 100% tested.
4
pF load ratings are based on DC loading and are provided as an indication of driver strength. High speed interfaces
require transmission line analysis to determine proper drive strength and termination.
5
All functional non-supply pins are internally clamped to V
SS
and their respective V
DD
.
6
Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values for positive and negative clamp voltages, then use the larger of the two values.
7
The power supply must maintain regulation within operating V
DD
range during instantaneous and operating maximum
current conditions. If positive injection current (V
in
> V
DD
) is greater than I
DD
, the injection current may flow out of V
DD
and could result in external power supply going out of regulation. Ensure that the external V
DD
load will shunt current
greater than maximum injection current. This will be the greatest risk when the MCU is not consuming power. Examples
are: if no system clock is present, or if clock rate is very low which would reduce overall power consumption. Also, the
system clock is not present during the power-up sequence until the PLL has attained lock.
