26.8.36 CLK_PLL_CONFIG
Description:
PLL Configuration Register
Address:
0x40261600
Offset:
0x1600
Retention:
Retained
IsDeepSleep:
Yes
Comment:
This register contains PLL configuration. There is a copy of this register for each PLL. PLL
circuit settings should not be changed while it is a selected clock (connected to logic). This
prevents clock glitches that can crash the logic.
Default:
0x20116
