3.7.6. Integration Test ATB Control 0 Register

The ITATBCTR0 characteristics are:

Purpose

Performs different functions depending on whether the access is a read or a write:

  • A read returns the value of the atvalidsn, atbytessn, and afreadysn signals, where the value of the Control Register at 0x000 defines n.

  • A write sets the value of the atvalidm, atbytesm, and afreadym signals.

Usage constraints

There are no usage constraints.

Configurations

This register is available in all configurations.
