NOTE:
EXTAL and XTAL routing resistances are less important than
capacitances. Using minimum width traces is an acceptable trade-off to
reduce capacitance.
This section applies to the 3L02H mask set, which refers to the newest
set of CGM improvements (to the MC68HC912D60A) with the Pierce
oscillator configuration enabled. The name for these devices is
MC68HC912D60P.
The Pierce oscillator architecture is shown in
component configuration for this oscillator is different to all previous
MC68HC912D60A configurations and the recommended components
may be different.
Please note carefully the connection of external capacitors and the
resonator in this diagram.
•
Minimize XTAL and EXTAL routing lengths to reduce EMC
issues.
