Note:
- Typical value
measured during characterization across voltage and
temperature.
- 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.
- These
parameters are characterized but not tested in
manufacturing.
