8.4.1.2.3 Mission State Configuration

The Mission States portion of the FSM engine manages the sequencing of power rails and external outputs in the user defined states. For the rest of Section 8.4.1 the Figure 8-42 is used as an example state machine which is defined through the configuration memory using the configuration FSM instructions.

GUID-20200827-CA0I-CPK6-8QXV-8ZDLLK7ZFJ7C-low.gif Figure 8-42 Example of a Mission State-Machine

Each power state (light blue bubbles in Figure 8-42) defines the ON or OFF state and the sequencing timing of the external regulators and GPIO outputs. This example defines 4 power states: STANDBY, ACTIVE, MCU ONLY, and DEEP_SLEEP/S2R states. The priority order of these states is as follows:

  1. ACTIVE
  2. MCU ONLY
  3. DEEP SLEEP/S2R
  4. STANDBY

The transitions between each power state is determined by the trigger signals source pre-selected from Table 8-15. These triggers are then placed in the order of priority through the trigger ID assignment of each trigger source. The critical error triggers are placed first, some specified as immediate triggers that can interrupt an on-going sequence. The non-error triggers, which are used to enable state transitions during normal device operation, are then placed according to the priority order of the state the device is transitioning to. Table 8-16 list the trigger signal sources, in the order of priority, used to define the power states and transitions of the example mission state machine shown in Figure 8-42. This table also helps to determine which triggers must be masked by the TRIG_MASK command upon arriving a pre-defined power state to produce the desired PFSM behavior.

Table 8-16 List of Trigger Used in Example Mission State Machine
Trigger ID Trigger Signal State Transitions Trigger Masked In Each User Defined Power State
STANDBY ACTIVE MCU ONLY DEEP SLEEP / S2R
0 IMMEDIATE_SHUTDOWN (1) From any state to SAFE RECOVERY
1 MCU_POWER_ERROR (1) From any state to SAFE RECOVERY

28-bit TRIG_MASK Value in Hex format: 0xFFE4FF8 0xFF18180 0xFF01270 0xFFC9FF0
(1) This is an immediate trigger.
(2) When an error occurs, which requires the device to enter directly to the SAFE RECOVERY state, the mask for this trigger must be removed while all other non-immediate triggers are masked. The device exits the mission states and the FFSM state machine takes over control of the device power states once this trigger is executed.
