WM8310
Pre-Production
PROGRAM - This is a special operating state which is used for programming the integrated OTP
memory with the device configuration data. The settings stored in the OTP define the device
configuration in the ON state, and also the time/sequencing data associated with ON/OFF power
state transitions. See Section 14 for details of the OTP features.
The valid power state transitions are illustrated in Figure 4.
Figure 4 Power States and Transitions
State transitions to/from the NO POWER state are controlled automatically by the internal supply
(VPMIC) voltage generated by LDO12. The device is in the NO POWER state when this voltage is
below the Power-On Reset (POR) threshold. See Section 24 for more details on Power-On Reset.
State transitions to/from the BACKUP state are controlled automatically by the internal supply
(VPMIC) voltage generated by LDO12. The device is in the BACKUP state when this voltage is below
the Device Reset threshold. See Section 24 for more details on Resets.
State transitions to/from the PROGRAM state are required to follow specific control sequences. See
Section 14 for details of the PROGRAM functions.
