EFM32LG Errata

Detailed Errata Descriptions

2. Detailed Errata Descriptions

2.1 BU_E105 — LFXO Missing Cycles During IOVDD Ramping

Description of Errata

LFXO missing cycles during IOVDD ramping when used in combination with Backup mode.

Affected Conditions / Impacts

When IOVDD is ramped, the dc-level of the XTAL signal changes, resulting in missed LFXO cycles and possible glitches on the LFXO

clock.

Workaround

Set PRESC in BURTC_CTRL to greater then 0 when ramping IOVDD in combination with Backup mode to avoid glitches on the

LFXO clock.

Resolution

There is currently no resolution for this issue.

2.2 CMU_E114 — Device Not Waking Up From EM2 When Using Prescaled Non-HFRCO Oscillator as HFCLK

Description of Errata

Device not waking up from EM2 when using prescaled non-HFRCO oscillator as HFCLK.

Affected Conditions / Impacts

If the device is running from any prescaled oscillator other than HFRCO as HFCLK and HFRCO is disabled, the device will not wake

up from EM2.

Workaround

Before entering EM2, clear CMU_CTRL_HFCLKDIV. Alternatively, enable HFRCO by setting CMU_OSCENCMD_HFRCOEN and

wait until CMU_STATUS_HFRCORDY is set.

Resolution

There is currently no resolution for this issue.

2.3 DAC_E109 — DAC Output Drift Over Lifetime

Description of Errata

The voltage output of the DAC might drift over time.

Affected Conditions / Impacts

When the device is powered and the DAC is disabled, stress on an internal circuit node can cause the output voltage of the DAC to

drift over time, and in some cases may violate the V

DACOFFSET

specification. If the DAC is always enabled while the device is pow-

ered, this condition cannot occur.

Workaround

Both in the startup initialization code and prior to disabling the DAC in application code, set the OPAnSHORT bit in DACn_OPACTRL

to a '1' for the corresponding DAC(s) used by the application. This will prevent the output voltage drift over time effect.

Resolution

There is currently no resolution for this issue.
