11.4 POWER STATE INTERRUPTS
11.5 POWER STATE GPIO INDICATION
w
These Reset conditions result in an OFF transition followed by an ON transition. These events are recorded as Reset events
in the ‘ON Source’ register.
SLEEP events are not recorded in the ‘OFF Source’ register.
Power State transitions are associated with a number of Interrupt event flags. Transitions to
BACKUP, SLEEP, ON or OFF states are indicated by the Interrupt bits described in Table 4. Each of
these secondary interrupts triggers a primary Power State Interrupt, PS_INT (see Section 23). This
can be masked by setting the mask bit(s) as described in Table 4.

Table 4 Power State Interrupts
The WM8310 can be configured to generate logic signals via GPIO pins to indicate the current
Power State. See Section 21 for details of configuring GPIO pins.
A GPIO pin configured as “ON state” output will be asserted when the WM8310 is in the ON state.
A GPIO pin configured as “SLEEP state” output will be asserted when the WM8310 is in the SLEEP
state.
