ARM DDI 0029G
Access type
Word
Halfword
Byte
For subword reads the value is placed in the ARM register in the least significant bits
regardless of the byte lane used to read the data. For example, a byte read on A[1:0] =
01 in a little-endian system means that the byte is read on bits D[15:8] but is placed in
the ARM register bits [7:0].
Writes
When the ARM7TDMI processor performs a byte or halfword write, the data being
written is replicated across the data bus, as shown in Figure 3-20 on page 3-28. 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.
