Read-write

0 (NOT_ENABLE) = the core reset signal “vddcore_nreset” is not affected when a brownout detection occurs.

1 (ENABLE) = the core reset signal, vddcore_nreset is asserted when a brownout detection occurs.

0 (ENABLE) = the core brownout detector is enabled.

1 (DISABLE) = the core brownout detector is disabled.

0 (ONREG_UNUSED) = Internal voltage regulator is not used (external power supply is used)

1 (ONREG_USED) = internal voltage regulator is used

Note:

0 (NO_EFFECT) = no effect. Clock selection depends on XTALSEL value.

1 (BYPASS) = the 32-kHz XTAL oscillator is selected and is put in bypass mode.

Should be written to value 0xA5. Writing any other value in this field aborts the write operation.
