AT91SAM9260 Errata - Revision “A” Parts
AT91SAM9260
Analog-to-digital Converter (ADC)
DRDY Bit Cleared
DRDY not Cleared on Disable
DRDY Possibly Skipped due to CDR Read
Possible Skip on DRDY when Disabling a Channel
GOVRE Bit is Not Updated
GOVRE Bit is Not Set when Reading CDR
Refer to
The DRDY Flag should be clear only after a read of ADC_LCDR (Last Converted Data Regis-
ter). A read of any ADC_CDRx register (Channel Data Register) automatically clears the DRDY
flag.
None
When reading LCDR at the same instant as an end of conversion, with DRDY already active,
DRDY is kept active regardless of the enable status of the current channel. This sets DRDY,
whereas new data is not stored.
None
Reading CDR for channel “y” at the same instant as an end of conversion on channel “x” with
EOC[x] already active, leads to skipping to set the DRDY flag if channel “x” is enabled.
Use of DRDY functionality with access to CDR registers should be avoided.
DRDY does not rise when disabling channel “y” at the same time as an end of “x” channel con-
version, although data is stored into CDRx and LCDR.
None.
Read of the Status Register at the same instant as an end of conversion leads to skipping the
update of the GOVRE (general overrun) flag. GOVRE is neither reset nor set.
For example, if reading the status while an end of conversion is occurring and:
None
When reading CDRy (Channel Data Register y) at the same instant as an end of conversion on
channel “x” with the following conditions:
1. GOVRE is active but DRDY is inactive, does not correspond to a new general overrun
2. GOVRE is inactive but DRDY is active, does correspond to a new general overrun con-
• EOC[x] already active,
