__STATIC_INLINE sl_status_t sl_si91x_power_manager_add_ps_requirement (sl_power_state_t state)

To add a requirement on power states.

The default state for the Power Manager is PS4. If any requirements are added, the Power Manager switches to the state if it is a valid transition. Before transitioning from one state to another, make sure to remove requirements of previous states if any were added. If an invalid state requirement is added, it returns SL_STATUS_INVALID_PARAMETER. If the Power Manager service is not initialized, it returns SL_STATUS_NOT_INITIALIZED. To initialize, call sl_si91x_power_manager_init. To get the requirements on all power states, call sl_si91x_power_manager_get_requirement_table. To know the current power state, use sl_si91x_power_manager_get_current_state.

  • sl_si91x_power_manager_init

Returns

• Status code indicating the result:

  • SL_STATUS_OK - Success.

It supports PS4, PS3, and PS2 only; it cannot enter sleep mode from any other active states. If any error occurs, it returns the error code and does not transition to sleep mode.

Note

• This function expects and calls a callback with the following signature: boolean_t sl_si91x_power_manager_is_ok_to_sleep(void). This function can be used to cancel a sleep action and handle the possible race condition where an ISR that would cause a wakeup is triggered right after the decision to call sl_si91x_power_manager_sleep() has been made.

This function also expects and calls a callback with the following signature: boolean_t sl_si91x_power_manager_isr_wakeup(void) after wakeup from sleep. The possible return values are:

• SL_SI91X_POWER_MANAGER_ISR_IGNORE

• SL_SI91X_POWER_MANAGER_ISR_SLEEP

• SL_SI91X_POWER_MANAGER_ISR_WAKEUP

Note

• It can end up in an infinite sleep-wakeup loop if continuously SL_SI91X_POWER_MANAGER_ISR_SLEEP return value is passed.

• Pre-conditions:

  • sl_si91x_power_manager_init

  • sl_si91x_power_manager_configure_ram_retention

  • sl_si91x_power_manager_set_wakeup_sources

Returns
