DescriptionResetTypeNameBit/Field
Use PLL
This bit controls whether the clock source is specified by the OSCSRC
field or the output of the PLL is provided to the system clock divider and
serves as the system clock source.
DescriptionValue
Clock source specified by OSCSRC field.0
Clock source specified by the PLL1
0RWUSEPLL28
PLL Source
This field specifies the PLL input clock source
DescriptionValue
PIOSC is the PLL input clock source0x0
reserved0x1-0x2
MOSC is the PLL input clock source0x3
Reserved0x4-0xFF
0RWPLLSRC27:24
Oscillator Source
This field specifies the oscillator source that becomes the oscillator clock
(OSCCLK) source, which is used when the PLL is bypassed during run
or sleep modes.
DescriptionValue
PIOSC is oscillator source0x0
reserved0x1
LFIOSC is oscillator source0x2
MOSC is oscillator source0x3
Hibernation Module RTC Oscillator (RTCOSC)0x4
reserved0x5-0xFF

Oscillator System Clock Divisor
This field specifies the system clock divisor value for the oscillator path.
This field is used when the USEPLL bit is 0.
