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