Access Support - NXP Semiconductors freescale KV4 Series Reference Manual

Functional description

The peripheral bridge manages all transactions destined for the attached slave devices and

generates select signals for modules on the peripheral bus by decoding accesses within

the attached address space.

21.7.1 Access support

All combinations of access size and peripheral data port width are supported. An access

that is larger than the target peripheral's data width will be decomposed to multiple,

smaller accesses. Bus decomposition is terminated by a transfer error caused by an access

to an empty register area.
