Access:
• BODRSTEN: Brownout Detector Reset Enable
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.
• BODDIS: Brownout Detector Disable
0 (ENABLE) = the core brownout detector is enabled.
1 (DISABLE) = the core brownout detector is disabled.
• ONREG: Voltage Regulator enable
0 (ONREG_UNUSED) = Voltage Regulator is not used
1 (ONREG_USED) = Voltage Regulator is used
• OSCBYPASS: Oscillator Bypass
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.
• KEY: Password Key
Should be written to value 0xA5. Writing any other value in this field aborts the write operation.
