• Inaccurate ADC conversion in differential mode with 200× gain
1. Inaccurate ADC conversion in differential mode with 200× gain
•
1. EEPROM read from application code does not work in Lock Bit Mode 3
EEPROM read from application code does not work in Lock Bit Mode 3.
With AVCC < 3.6V, random conversions will be inaccurate. Typical absolute accuracymay
reach 64 LSB.
Problem Fix/Workaround
None
Not sampled
When the Memory Lock Bits LB2 and LB1 are programmed to mode 3, EEPROM read does
not work from the application code.
Problem Fix/Work around
Do not set Lock Bit Protection Mode 3 when the application code needs to read from
EEPROM.
