Note:

  1. Conditions:

    • All peripherals are disabled using PMD bits.
    • Disable the JTAG port.
    • RF system is turned OFF.
    • Disable CMCC.
    • Enable PreFetch cache.
    • All GPIOs are set as inputs and pulled up.
    • PB1, PB2, PB4 and PB5 clocks are divided by 2, while PB3 clock is divided by 20.
    • WCM memories are configured in Retention + NAP mode.
    • DSU is disconnected.
    • The RF system is in power-down configuration.
  2. Entry to Sleep mode enabled and WFI instruction executed.
    • On exit by Wake-up source (RTCC), verify the RCON status to ensure the system is 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 divided by 8 and POSC 16 MHz clock is disabled.
