The crystal should be a fundamental mode type - not
an overtone. The fundamental mode crystal permits
a simpler oscillator circuit with no additional filter
components and is less likely to generate spurious
responses. The crystal specification is as follows.
Frequency:
Tolerance:
Oscillation Mode:
Resonance Mode:
Load Capacitance:
Maximum Series Resistance:
Approximate Drive Level:

Reset Circuit
A simple power up reset circuit with about a 50us
reset low time is shown in Figure 7. Resistor R
P
is for
protection only and limits current into the RST pin
during power down conditions. The reset low time is
not critical but should be greater than 300ns.
