1
Must be connected together as close the device as possible for latch-up immunity.
2
Reference voltage can be internally selected between 1.23V and 1.65V, see section 8.7.2.
3
The maximum sample rate that can be played with correct speed is XTALI/256 (or XTALI/512 if
SM CLK RANGE is set). Thus, XTALI must be at least 12.288 MHz (24.576 MHz) to be able to play
48 kHz at correct speed.
4
Reset value is 1.0×. Recommended SC MULT=3.5×, SC ADD=1.0× (SCI CLOCKF=0x8800).
Do not exceed maximum specification for CLKI.
