PLL configuration registers (address 0x52; 0x53; 0x54; 0x55;

0x56; 0x57)

By default, the STA381BWS is able to configure the embedded PLL automatically

depending on the MCS bits (reg 0x00). For certain applications and to provide flexibility to

the user, a manual PLL configuration can be used (setting PLL_DIRP to ‘1’)

The output PLL frequency formula is:

where Fin is the input clock frequency from the pad.
