1 Errata
This document contains information on the errata of the latest revision of this device. For errata on older revisions, please refer to the errata history for the
device. The device datasheet explains how to identify chip revision, either from package marking or electronically.
In addition to the errata noted below, the errata for the ARM Cortex-M3 r2p1 (www.arm.com) also applies to this device.
1.1 Chip revision C
Table 1.1. Erratas
ID
Title/Problem
Effect
Fix/Workaround
DMA_E101
EM2 with WFE and DMA
In EM2, when sleeping with WFE (Wait for Event), an interrupt from the DMA will not wake up the system.
Use WFI (Wait for Interrupt) or EM1 instead.
When using edge detect in PRS on signals from ACMP,
GPIO, RTC, LETIMER, LESENSE, VCMP and BURTC
edges can be missed.
Do not use edge detect on ACMP, GPIO, RTC, LETIMER,
LESENSE, VCMP and BURTC.
When DEBUGRUN is disabled, and the capture input is
HIGH it is possible to wrongly trigger a capture event by halting the MCU and starting it again (for instance by setting a
breakpoint).
Enable DEBUGRUN when using a debugger.
WFE does not work for the DMA in
EM2.
PRS_E101
Edge detect on GPIO/ACMP
Edge detect on peripherals with asynchronous edges might be missed.
TIMER_E102
Timer capture and debugger
Timer capture triggered when timer is
halted by debugger.
USART_E112
USART AUTOTX continues to transmit even with full RX buffer
WDOG_E103
WDOG EM2 detection with LFXO
digital/sine input
When AUTOTX in USARTn_CTRL or AUTOTXEN in
USARTn_TRIGCTRL is set, the USART will continue to
transmit data even after the RX buffer is full. This may cause
USART AUTOTX continues to transmit the RX buffer to overflow if the data is not read out in time.
even with full RX buffer.
The WDOG will mistake EM2 for EM3
if using LFXO with digital or sine input.
No known workaround.
When the WDOG is using LFXO with digital or sine input as a When using LFXO with digital/sine input, EM3RUN must be
clock source, it will mistake EM2 for EM3. The EM2RUN and set to keep the WDOG running in EM2.
EM3RUN bits of WDOG_CTRL will behave accordingly.
