Errata: For information on silicon errata, see “Errata” on page 48. 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. 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.
