DS2433
OVERDRIVE SKIP ROM [3Ch]
On a single-drop bus this command can save time by allowing the bus master to access the memory
functions without providing the 64-bit ROM code. Unlike the normal Skip ROM command the Overdrive
Skip ROM sets the DS2433 in the Overdrive Mode (OD = 1). All communication following this
command has to occur at Overdrive Speed until a Reset Pulse of minimum 480 ? s duration resets all
devices on the bus to regular speed (OD = 0).
When issued on a multidrop bus this command will set all Overdrive-supporting devices into Overdrive
mode. To subsequently address a specific Overdrive-supporting device, a Reset Pulse at Overdrive speed
has to be issued followed by a Match ROM or Search ROM command sequence. This will speed up the
time for the search process. If more than one slave supporting Overdrive is present on the bus and the
Overdrive Skip ROM command is followed by a read command, data collision will occur on the bus as
multiple slaves transmit simultaneously (open drain pulldowns will produce a wire-AND result).
OVERDRIVE MATCH ROM [69h]
The Overdrive Match ROM command, followed by a 64-bit ROM sequence transmitted at Overdrive
Speed, allows the bus master to address a specific DS2433 on a multidrop bus and to simultaneously set it
in Overdrive Mode. Only the DS2433 that exactly matches the 64-bit ROM sequence will respond to the
subsequent memory function command. Slaves already in Overdrive mode from a previous Overdrive
Skip or Match command will remain in Overdrive mode. All overdrive-capable slaves will return to
regular speed at the next Reset Pulse of minimum 480 ? s duration. The Overdrive Match ROM command
can be used with a single or multiple devices on the bus.
