Address:
Access:
• VROFF: Voltage Regulator Off
0 (NO_EFFECT) = no effect.
1 (STOP_VREG) = if KEY is correct, asserts vddcore_nreset and stops the voltage regulator.
• XTALSEL: Crystal Oscillator Select
0 (NO_EFFECT) = no effect.
1 (CRYSTAL_SEL) = if KEY is correct, switches the slow clock on the crystal oscillator output.
• KEY: Password
Should be written to value 0xA5. Writing any other value in this field aborts the write operation.
