6. EEPROM read from application code does not work in Lock Bit Mode 3
•
1. High current consumption in sleep mode.
Not sampled.

1.
High current consumption in sleep mode
Non-Read-While-Write area of flash not functional
Part does not work under 2.4 Volts
Incorrect ADC reading in differential mode
Internal ADC reference has too low value
IN/OUT instructions may be executed twice when Stack is in external RAM
EEPROM read from application code does not work in Lock Bit Mode 3
When the Memory Lock Bits LB2 and LB1 are programmed to mode 3, EEPROM
read does not work from the application code.
Problem Fix/Workaround
Do not set Lock Bit Protection Mode 3 when the application code needs to read from
EEPROM.
No known errata.
Not sampled.
If a pending interrupt cannot wake the part up from the selected sleep mode, the
current consumption will increase during sleep when executing the SLEEP instruc-
tion directly after a SEI instruction.
Problem Fix/Workaround
Before entering sleep, interrupts not used to wake the part from the sleep mode
should be disabled.
The Non-Read-While-Write area of the flash is not working as expected. The prob-
lem is related to the speed of the part when reading the flash of this area.
Problem Fix/Workaround
- Only use the first 248K of the flash.
- If boot functionality is needed, run the code in the Non-Read-While-Write area at
maximum 1/4th of the maximum frequency of the device at any given voltage. This
is done by writing the CLKPR register before entering the boot section of the code.
Non-Read-While-Write area of flash not functional
