4. Module: Electrical Specifications
The operating frequency range for extended tem-
perature devices has been changed.
The maximum external clock frequency (EC and
ECIO modes) and oscillator frequency (HS mode)
for extended temperature devices has been
changed to 25 MHz. When the PLL is used
(HS+PLL mode), the maximum clock and oscilla-
tor frequency has been changed to 6.25 MHz.
Other values of related parameters have changed
accordingly.
Table 21-4, Parameters 1 and 1A of the Device
Data Sheet are amended in part, as follows
