Must be connected together as close the device as possible for latch-up immunity.
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.

Reset value is
1.0×.
Recommended SC_MULT=3.0×, SC_ADD=1.0× (SCI_CLOCKF=0x9000).
