When pll is used.
The LSI support audio PLL function that can generate precise audio clock from wide range of clock frequency. Then, it can
be realize audio function without external clock generator for audio. The LSI supports following cases.
■ case 1: PLLISEL=0 or 2, MST=0, MCLKOE=0
Audio PLL generate system clock as 256fs from LRCLK
