Note:
  1. Typical value measured at 25°C and 3.3V.
  2. The test conditions are as follows:
    • All GPIO are input and pulled up.
    • All peripherals disabled with PMD bits.
    • All PB clocks are divided by 16.
    • LPRC is set as LPCLK.
    • SOSC is disabled.
    • CLDO is configured at lowest possible voltage (VREG Trim = 0x07).
    • PMU is configured to the Buck PSM mode on the Sleep Mode Entry.
    • Cache is enabled and configured wait time as 0xF.
    • WCM memories configured in Retention + NAP mode.
    • DSU is disconnected.
    • RF system is in low power configuration.
    • Entry to the Sleep mode is enabled and WFI instruction is executed.
    • On exit by External interrupt, verified RCON status to ensure system was in Sleep mode.
    • In XTAL ON mode - PMU Buck clock is derived from POSC 16 MHz and scaled to 1 MHz. FRC is OFF.
    • In XTAL OFF mode - PMU is clocked from FRC and XTAL 16 MHz clock is disabled and clock configuration in CRU changed to FRC.
  3. These parameters are characterized but not tested in manufacturing.
