PLL Enable
0 = (Valid for slave and master mode)—The frequency of LRCLK is set by the NHI and NLO divider
1 = (Valid for slave mode only)—Used when the audio master generates an LRCLK not selectable
Rapid Lock Mode
To enable rapid lock mode set NHI and NLO to the nearest desired ratio and set NLO[0] = 1 (Register
0x05, bit 0) before setting the PLL mode bit.
LRCLK Divider
NHI and NLO control a 15-bit clock divider (N). When the PLL = 0 and FREQ = 00, the frequency of
LRCLK is determined by the clock divider. See Table 4 for common N values.
