AW: [avr-gcc-list] small crystal/ceramic resonator

[Stumpf Michael]

Hi,
we used an CSTCC 4,00 MHz Resonator with internal caps *and* external 33p
caps 
for EMS and observed that frequency dropped below 4.00 MHz to about 3.95
MHz.
Could be a subject if baud rate detection is performed.

regards, Michael
