26. Errata
The revision letters in this section refer to the revision of the corresponding ATtiny24/44/84
device.
26.1 ATtiny24
26.1.1 Rev. D – E
No known errata.
26.1.2 Rev. C
•
Reading EEPROM when system clock frequency is below 900 kHz may not work
1. Reading EEPROM when system clock frequency is below 900 kHz may not work
Reading data from the EEPROM at system clock frequency below 900 kHz may result in
wrong data read.
Problem Fix/Work around
Avoid using the EEPROM at clock frequency below 900 kHz.
26.1.3 Rev. B
•
EEPROM read from application code does not work in Lock Bit Mode 3
• Reading EEPROM when system clock frequency is below 900 kHz may not work
1. 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/Work around
Do not set Lock Bit Protection Mode 3 when the application code needs to read from
EEPROM.
2. Reading EEPROM when system clock frequency is below 900 kHz may not work
Reading data from the EEPROM at system clock frequency below 900 kHz may result in
wrong data read.
Problem Fix/Work around
Avoid using the EEPROM at clock frequency below 900 kHz.
26.1.4 Rev. A
Not sampled.
