XTALI
The maximum sample rate that can be played with correct speed is XTALI/128. With 11 MHz
XTALI sample rates over 85937 Hz are played at 85937 Hz.
2
When full speed (FS) or high speed (HS) USB is used it is recommended that XTAL of
12.0MHz 0r 12.288MHz is used.
3
The 32kHz crystal is optional, but required for RTC time
counter.
