20. Unless otherwise noted, test conditions are as follows: All zeros input, slave mode, sample
21. RESET pin 25 held LO, all clocks and data lines are held LO.
22. RESET pin 25 held HI, all clocks and data lines are held HI.
23. VL current will slightly increase in master mode.
(Note 22)
rate = 48 kHz; No load. Digital (VD) and logic (VL) supply current will vary depending on speed mode
and master/slave operation.
