Details include trigger conditions, devices affected, and proposed workaround. Notes 1. Errata: The worst case IMO frequency deviation when operated below 0 C and above +70 C and within the upper and lower datasheet temperature range is 5%. 2 2 2. Errata: The I C block exhibits occasional data and bus corruption errors when the I C master initiates transactions while the device is transitioning in to or out of sleep mode.
