10.8.5 Read - Lock - Write
The read-lock-write sequence is generated by a SWP instruction. On the bus it
consists of a read access followed by a write access to the same address, and both
are treated as nonsequential accesses. The cycle is differentiated by the
LOCK
has the timing of address, ie. it goes HIGH in the HIGH phase of
start of the read access. However, it always goes LOW at the end of the write access,
even if the following cycle is an idle cycle (unless of course the following access was
a read-lock-write sequence).
