5.3.2.3 SLEEP and WAKE Requests

The device transitions from the ACTIVE to the SLEEP state after receiving a SLEEP request. Upon this request, internal resources as well as user-defined resources will enter the low-power mode as predefined by the user. The states of the resources during ACTIVE and SLEEP states are defined in the LDO*_CTRL and SMPSx_CTRL registers.

Table 5-4 lists the SLEEP requests. Any of theses events trigger the ACT2SLP sequence unless pending interrupts (unmasked) are present. Once the device enters the SLEEP state, only an interrupt or an NSLEEP signal can generate a WAKE request to wake up the device (exit from the SLEEP state). A WAKE request (only during the SLEEP state) wakes up the device and triggers a SLP2ACT or a SLP2OFF power sequence.

Table 5-4 SLEEP Requests

EVENT MASKABLE POLARITY COMMENT
NSLEEP (pin) Yes (Default: Masked) Low Level sensitive

For each resource, a transition from the ACTIVE state to the SLEEP state or from the SLEEP state to the ACTIVE state is controlled in two different ways which are described as follows:

  • Through EPC sequencing (ACT2SLP or SLP2ACT power sequence) when the resource is associated to the NSLEEP signal.
  • Through direct control of the resource power mode (ACTIVE or SLEEP) in which case the user can bypass SLEEP and WAKE sequencing by having resources assigned to two external control signals (ENABLE1 and ENABLE2). These signals have a direct control on the power modes (ACTIVE or SLEEP) of any resources associated to them and they trigger an immediate switch from one mode to the other, regardless of the EPC sequencing.

Therefore, all resources can be associated to three external pins (NSLEEP, ENABLE1, and ENABLE2) and can switch between the SLEEP and ACTIVE states. Table 5-5 outlines the type of state transition each resource undergoes according to the logic combination of the NSLEEP, ENABLE1 and ENABLE2 assignments.

  1. Notes:
    • The polarity of the NSLEEP, ENABLE1, and ENABLE2 signals is configurable through the POLARITY_CTRL register. By default:
      • ENABLE1 and ENABLE2 are active high, meaning a transition from 0 to 1 requests a transition from SLEEP state to ACTIVE state.
      • NSLEEP is active low, meaning a transition from 1 to 0 requests a transition from ACTIVE state to SLEEP state.
    • Resource assignments to the NSLEEP, ENABLE1, and ENABLE2 signals are configured in the ENABLEx_YYY_ASSIGN and NSLEEP_YYY_ASSIGN registers (where x = 1 or 2 and YYY = RES, SMPS, or LDO).
    • Several resources can be assigned to the same ENABLE signal (ENABLE1 or ENABLE2) and therefore, when triggered, they all switch their power mode at the same time.
    • When resources are assigned only to the NSLEEP signal, the respective switching order is controlled and defined in the power sequence.
    • When a resource is not assigned to any signal (NSLEEP, ENABLE1, or ENABLE2), it never switches from the ACTIVE state to the SLEEP state. The resource always remains in ACTIVE mode.
