1 kΩ
* When no external master clock is supplied to the part, both input and output must be set to salve mode
for the part to operate properly. This is done by connecting the MS_SEL pin to ground through a resis-
tance of 0Ω to 1 kΩ ± 1% as stated in Table 1, “Serial Audio Port Master/Slave and Clock Ratio Select
Startup Options (MS_SEL),” on page 13
** The connection (VL or GND) and value of these two resistors determines the mode of operation for the
input and output serial ports as described in Table 1, “Serial Audio Port Master/Slave and Clock Ratio
Select Startup Options (MS_SEL)", Table 2, “Serial Audio Input Port Startup Options (SAIF)", and
Table 3, “Serial Audio Output Port Startup Options (SAOF)", all on page 13.
