Reading EEPROM at low frequency may not work for frequencies below 900 kHz

1. Reading EEPROM at low frequency may not work for frequencies below 900 kHz Reading data from the EEPROM at low internal clock frequency may result in wrong data read when Unlock Microcontroller.

Problem Fix/Workaround

Avoid using the EEPROM at clock frequency below 900kHz. PLL not locking

EEPROM read from application code does not work in Lock Bit Mode 3 if Unlock Microcontroller

Reading EEPROM at low frequency may not work for frequencies below 900 kHz

Timer Counter 1 PWM output generation on OC1B- XOC1B does not work correctly before Unlock Microcontroller

1. PLL not locking

When at frequencies below 6.0 MHz, the PLL will not lock

Problem fix / Workaround When using the PLL, run at 6.0 MHz or higher.

2. EEPROM read from application code does not work in Lock Bit Mode 3 after Unlock Microcontroller

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 when Unlock Microcontroller.

3. Reading EEPROM at low frequency may not work for frequencies below 900 kHz

Reading data from the EEPROM at low internal clock frequency may result in wrong data read.

Problem Fix/Workaround

Avoid using the EEPROM at clock frequency below 900kHz if Unlock Microcontroller.

4. Timer Counter 1 PWM output generation on OC1B – XOC1B does not work correctly

Timer Counter1 PWM output OC1B-XOC1B does not work correctly. Only in the case when the control bits, COM1B1 and COM1B0 are in the same mode as COM1A1 and COM1A0, respectively, the OC1B-XOC1B output works correctly before Unlock Microcontroller.

Problem Fix/Work around

The only workaround is to use same control setting on COM1A(1:0) and COM1B(1:0) control bits, see table 14-4 in the data sheet. The problem has been fixed for Tiny45 rev D after Unlock Microcontroller.
