  • Contact your T.I. representative to get a copy of the ARM Cortex-A8 (AT400/AT401/AT490) Errata Notice.

Definitions of Category 1 and Category 2:

  • Category 1 Behaviour that is impossible to work around and that severely restricts the use of the product in all, or the majority of applications, rendering the device unusable.
  • Category 2 Behaviour that contravenes the specified behaviour and that might limit or severely impair the intended use of specified features, but does not render the product unusable in all or the majority of applications.
