3. VDDIN current consumption increase above 1.8V
4. Increased Power Consumption in VDDIO in sleep modes
Do not enter Shutdown mode.
Fix/Workaround
None.
When VDDIN increases above 1.8V, current on VDDIN increases with up to 40µA.
Fix/Workaround
None.
If the OSC0 is enabled in crystal mode when entering a sleep mode where the OSC0 is dis-
abled, this will lead to an increased power consumption in VDDIO.
Fix/Workaround
Solution 1: Disable the OSC0 bt writing a zero to the Oscillator Enable bit in the System
Control Interface (SCIF) Oscillator Control Register (SCIF.OSC0CTRL.OSCEN) before
going to any sleep mode where the OSC0 is disabled
Solution 2: Pull down or up XIN0 and XOUT0 with 1Mohm resistor.
