Oscillator 0 might be automatically selected for several reasons:
Oscillator 0 might be the system clock or the source clock for
either PLL0 or DFPLL. It might also be needed if OSC0 is the source
clock for GCLK9. By selecting SAM34_OSC0, you can also force the
clock to be enabled at boot time for other uses.

default n
---help---
The 32K oscillator might be automatically selected for several
reasons: The 32K oscillator may be the source clock for DFPLL0 or
the source clock for GLK9 that might be used to driver PLL0. By
selecting SAM34_OSC32K, you can also force the clock to be enabled
at boot time. OSC32 may needed by other devices as well (AST, WDT,
PICUART, RTC).
config SAM34_RC80M

default n
---help---
The 80MHz RC oscillator might be automatically selected for several
reasons: This might be the system clock or the source clock for the
DFPLL or it could be the source for GCLK9 that drives PLL0. By
selecting SAM34_RC80M, you can also force the clock to be enabled at
boot time for other uses.

default n
---help---
The fast RC oscillator might be automatically selected for several
reasons: The 12/8/4 fast RC oscillator may be used as the system
clock or as the source for GLCK9 that drives PLL0. If not then, it
may be enabled by setting the SAM34_RCFASTxM configuration variable.

The 1MHz RC oscillator might be automatically selected for several
reasons: The 1MHz RC oscillator may be used as the system block or
may be the source clock for GLCK9 that drives PLL0. By selecting
SAM34_RC1M, you can also force the clock to be enabled at boot time
for other purposes.

---help---
The WDT can be enabled at reset. This is controlled by the WDTAUTO
fuse. The WDT will be set in basic mode, RCSYS is set as source for
CLK_CNT, and PSEL will be set to a value giving Tpsel above 100 ms
(SAM4L)
This setting informs that start-up logic that the watchdog is
enabled.

---help---
If the WDT can be enabled at reset then this setting may be used to
configure and disable the watchdog timer very early in the boot
sequence.
