AT32UC3A
If the ADC sleep mode is activated when the ADC is idle the ADC will not enter sleep mode
before after the next AD conversion.
before after the next AD conversion.
Fix/Workaround
Activate the sleep mode in the mode register and then perform an AD conversion.
Activate the sleep mode in the mode register and then perform an AD conversion.

ABDAC
1. Audio Bitstream DAC is not functional.
Fix/Workaround
Do not use the ABDAC on revE.
Do not use the ABDAC on revE.
41.5.12
FLASHC
1. The address of Flash General Purpose Fuse Register Low (FGPFRLO) is 0xFFFE140C
on revE instead of 0xFFFE1410.
Fix/Workaround
None.
Fix/Workaround
None.
2. The command Quick Page Read User Page(QPRUP) is not functional.
Fix/Workaround
None.
None.
3. PAGEN Semantic Field for Program GP Fuse Byte is WriteData[7:0], ByteAddress[1:0]
on revision E instead of WriteData[7:0], ByteAddress[2:0].
Fix/Workaround
None.
Fix/Workaround
None.
4. On AT32UC3A0512 and AT32UC3A1512, corrupted read in flash after FLASHC WP,
EP, EA, WUP, EUP commands may happen
- After a FLASHC Write Page (WP) or Erase Page (EP) command applied to a page in a
given half of the flash (first or last 256 kB of flash), reading (data read or code fetch) the
other half of the flash may fail. This may lead to an exception or to other errors derived from
this corrupted read access.
- After a FLASHC Erase All (EA) command, reading (data read or code fetch) the flash may
fail. This may lead to an exception or to other errors derived from this corrupted read access.
- After a FLASHC Write User Page (WUP) or Erase User Page (EUP) command, reading
(data read or code fetch) the second half (last 256 kB) of the flash may fail. This may lead to
an exception or to other errors derived from this corrupted read access.

Fix/Workaround
Flashc WP, EP, EA, WUP, EUP commands: these commands must be issued from RAM or
through the EBI. After these commands, read twice one flash page initialized to 00h in each
half part of the flash.

RTC
1. Writes to control (CTRL), top (TOP) and value (VAL) in the RTC are discarded if the
RTC peripheral bus clock (PBA) is divided by a factor of four or more relative to the
HSB clock.
Fix/Workaround
Do not write to the RTC registers using the peripheral bus clock (PBA) divided by a factor of
four or more relative to the HSB clock.

Fix/Workaround

four or more relative to the HSB clock.
