1. Reading EEPROM when system clock frequency is below 900 kHz may not work
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.
