Figure 73.
Circuit Board design should observe the following parameters.
•
•
•
•
Signal line layout must avoid areas marked with the shaded area of Figure
73.
Locate the crystal and load capacitors as close to the IC as physically
possible to reduce noise.
Signal lines must not run parallel to the clock oscillator inputs. In
particular, the clock input circuitry and the system clock output (pin 64)
must be separated as much as possible.
V
circuitry.
Resistivity between XTAL or EXTAL and the other pins must be
greater than 10M ohms.
CC
Crystal
power lines must be separated from the clock oscillator input
