Synchronous bus arbitration is not recommended. Use Asynchronous mode whenever possible.
An expression is used to compute the maximum or minimum value listed, as appropriate. For timing 223, the minimum is an
absolute value.
T212 is valid for Address Trace mode when the ATE bit in the Operating Mode Register is set. BR is deasserted for internal
accesses and asserted for external accesses.
