Advance Information
254
PLLMODE — Clock Mode Bit
PLLSEL — PLL Select Bit
PLLREF — PLL Reference Bit
LOCKS — Sticky PLL Lock Bit
The MODE bit is configured at reset and reflects the clock mode as
shown in
The PLLSEL bit is configured at reset and reflects the PLL mode as
shown in
The PLLREF bit is configured at reset and reflects the PLL reference
source in normal PLL mode as shown in
PLLMODE:PLLSEL:PLLREF
The LOCKS flag is a sticky indication of PLL lock status.
The lock detect function sets the LOCKS bit when the PLL achieves
lock after:
