7. PLL block
The PLL block generates a 14.112 MHz master clock (MCK2) that is used for all three frequencies; 32, 44.1, and
48 kHz, when either 32 or 48 kHz is specified as the input data sampling frequency.
STOP pin setting
UNLK pin
The UNLK pin is high during unlocked periods and during the 1024/fs (seconds) required for the unlocked to locked
transition. The LSI performs the same processing during the locked to unlocked transition as it does when MUTE is
high.
