Writes
When the ARM9E-S performs a byte or halfword write, the data being written is
replicated across the bus, as illustrated in Figure 4-7. The memory system can use the
most convenient copy of the data. A writable memory system must be capable of
performing a write to any single byte in the memory system. This capability is required
by the ARM C compiler and the Debug tool chain.
