• VRDEEP: Voltage Regulator Deep Mode
0 = Voltage Regulator Deep Mode is disabled.
1 = Voltage Regulator Deep Mode is enabled.
• VRVDD: Voltage Regulator Output Voltage Selection
• VRRSTEN: Voltage Regulation Loss Reset Enable
0 = Losing the voltage regulation does not affect the core reset signal, vddcore_nreset.
1 = Losing the voltage regulation asserts the core reset signal, vddcore_nreset.
• SRAMON: SRAM On
0 = SRAM (Backup) switched off in backup mode.
1 = SRAM (Backup) switched on in backup mode.
• RTON: Real Time Clock Alarm Power Switch On
0 = Real Time Clock Alarm switched off.
1 = Real Time Clock Alarm switched on.
• FLASHON: Flash Memory Power Switch On
0 = Flash Memory switched off.
1 = Flash Memory switched on.
• OSCBYPASS: Oscillator Bypass
0 = No effect. Clock selection depends on XTALSEL value.
1 = 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.
