3.4 BATMON_01

Incorrect temperature measurement

Revisions Affected

See Table 1-1

Description

BATMON can report incorrect temperatures when hysteresis is enabled. To prevent potential incorrect temperature reports, the user must always disable BATMON hysteresis.

Workaround

Hysteresis is controlled by the PMUD.CLT[2] HYST_EN bit.

Hysteresis is enabled by default (reset value = 1) and, therefore, must actively be disabled during boot.

Hysteresis can be disabled by clearing the PMUD.CLT[2] HYST_EN bit using the following command:

HWREG( PMUD_BASE + PMUD_O_CTL ) = ( PMUD_CTL_CALC_EN | PMUD_CTL_MEAS_EN )

This workaround is incorporated into the SimpleLink™ Low Power F3 software development kit (SDK) version 8.10 and newer.
