1.2. AMBA compatibility

The PrimeCell SCI complies with the AMBA Specification (Rev 2.0) onwards. The fundamental differences from the AMBA Specification Revision D are:

This document assumes little-endian memory organization, where bytes of increasing significance are stored in increasing addresses in memory, and hence low-order bytes are transferred on the low-order bits of the data bus. This block can also be used in a system with a big-endian memory organization, and several methods of achieving this are described in the PrimeCell Smart Card Interface (PL130) Integration Manual.
