Silicon Errata Issues

Module: Resets (BOR)

A device Reset may occur if the BOR is disabled

and

immediately

re-enabled

software

(RCON<14> is cleared, and then immediately

set).

Work around

It is recommended that several NOP instructions

be added to a BOR disable/enable sequence.

Alternatively, place several instructions or a

short routine between the instructions to disable

and enable the BOR.

Affected Silicon Revisions

Module: Core (Deep Sleep)

Deep Sleep wake-up sources may be ignored if

they occur just prior to entry into Deep Sleep

mode. As a result, the device may enter Deep

Sleep mode when it should not.

Work around

If possible, configure external Deep Sleep

wake-up sources to repeat themselves once. If

the device does enter Deep Sleep, the second

occurrence of the wake-up source will wake the

device.

Alternatively, synchronize the entry into Deep

Sleep with external wake-up sources, where

possible.

Affected Silicon Revisions

Module: Comparator

The maximum value for the input offset voltage

(specification

D300,

VIOFF),

shown

Table 26-12 of the Device Data Sheet, has

changed for this silicon revision. The new value

is shown in Table 3 (changes in bold).

Work around

None.
