NAME
NI1/
NI2
Exact Integer Mode
Overrides PLL1 and NI1 and configures a specific PCLK to LRCLK ratio.
PLL Mode Enable (Slave Mode Only)
PLL1/PLL2 enables a digital PLL that locks on to the externally supplied LRCLK frequen-
cy and automatically sets the LRCLK divider (NI1/NI2).
0 = Disabled
1 = Enabled
Normal Mode LRCLK Divider
When PLL1/PLL2 = 0, the frequency of LRCLK is determined by NI1/NI2. See Table 12
for common NI values.

Rapid Lock Mode
Program NI1/NI2 to the nearest valid ratio and set NI1[0]/NI2[0] when PLL1/PLL2 = 1
to enable rapid lock mode. Normally, the PLL automatically calculates and dynamically
adjusts NI1/NI2. When rapid lock mode is properly configured, the PLL starting point is
much closer to the correct value, thus speeding up lock time. Wait one LRCLK period
after programming NI1/NI2 before setting PLL1/PLL2 = 1.
