1 Must be connected together as close the device as possible for latch-up immunity.
2 The maximum sample rate that can be played with correct speed is XTALI/256.
Thus, XTALI must be at least 12.288 MHz to be able to play 48 kHz at correct speed.
For other implications rising from not using a 12.288 MHz clock, see Chapter 7.4.5.
3 Reset value is 1.0×. Recommended SC MULT=4.0×.
Performance may be poor if SC MULT< 3.5.
4 52.0 MHz is the maximum clock for the full CVDD range.
(4.0 × 12.288 MHz=49.152 MHz or 3.5 × 13.0 MHz=45.5 MHz)
