17. Voltage Regulator Mode Controller (VREG)
17.1
Overview
The Voltage Regulator Mode Controller contains one Read/Write register, the Voltage Regulator Mode Register.
Its offset is 0x60 with respect to the System Controller offset.
This register controls the Voltage Regulator Mode. Setting PSTDBY (bit 0) puts the Voltage Regulator in Standby
Mode or Low-power Mode. On reset, the PSTDBY is reset, so as to wake up the Voltage Regulator in Normal
Mode.
