1 _{Must be connected together as close the device as possible for latch-up immunity.}
2 _{4.0 V is required for compliant USB level.}
3 _{Regulator output of the device.}
4 _{The maximum sample rate that can be played with correct speed is XTALI/256. With 12 MHz XTALI}
sample rates over 46875 Hz are played at 46875 Hz.
5 _{To be able to use USB, XTALI must be 12 MHz.}
