Spurious temperature update interrupts from BATMON in standby

Revisions Affected

B

Description

BATMON can issue spurious temperature update interrupts when PMUD.EVENT.TEMP_UPDATE is used as a wake-up source from standby.

Workaround

Instead of using PMUD.EVENT.TEMP_UPDATE as the wake-up source, PMUD.EVENT.TEMP_OVER_UL (current temperature over a set upper limit) or PMUD.EVENT.TEMP_BELOW_LL (current temperature below a set lower limit) shall be considered.

When using PMUD.EVENT.TEMP_OVER_UL or PMUD.EVENT.TEMP_BELOW_LL as wake-up interrupts, these are the other settings that have to be enabled:

  • Select GLDO as the source for VDDR regulation by setting PMCTL.VDDRCTL.SELECT to 0x0.
Note:

This causes a slight increase in standby power consumption. Please check the ‘Power Consumption – Power Modes’ section of the data sheet for exact details.

  • Set SYS0.TMUTE4.RECHCOMPREFLVL to 0x2
  • Set SYS0.TMUTE5.GLDOISSET to 0x1E

This workaround would be incorporated into future releases of SimpleLink™ Low Power F3 software development kit (SDK).
