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.
3
Reset value is 1.0×. Recommended SC_MULT=3.0×, SC_ADD=1.0× (SCI_CLOCKF=0x9000).
4
52.0 MHz is the maximum clock for the full CVDD range.
(4.0 × 12.288 MHz=49.152 MHz or 4.0 × 13.0 MHz=52.0 MHz)
