Bit 4 - ENABLE SUPPLY (selects between LOW POWER mode and WAIT mode):
• 0 = WAIT mode allowed, activated when LOW_PWR pin = 1 and VDCDC1 < 3 >= 1.
• 1 = The TPS65014 enters LOW POWER mode when LOW_PWR pin = 1 and VDCDC1 < 3 >= 1.
Bit 3 - ENABLE LP:
• 0 = disables the low power function of the LOW_PWR pin.
• 1 = enables the low power function of the LOW_PWR pin.
Bit 2 - MAIN DISCHARGE:
• 0 = disables the active discharge of the VMAIN converter output.
• 1 = enables the active discharge of the VMAIN converter output, when the converter is disabled (i.e., in
WAIT mode).
Bit 1-Bit 0 - MAIN<1:0>: The VMAIN converter output voltages are set according to the following table, with the
default values in bold set by the DEFMAIN pin. The default voltage can subsequently be overwritten via the serial
interface after start-up.

The VDCDC2 register is used to program the VCORE switching converter output voltage. It is programmable in 8
steps between 0.85 V and 1.8 V. The default value is governed by the DEFCORE pin; DEFCORE=0 sets an
output voltage of 1.5 V. DEFCORE=1 sets an output voltage of 1.8 V.
Bit 7 - LP_COREOFF:
• 0 = VCORE converter is enabled in low power mode.
• 1 = VCORE converter is disabled in low power mode.
