17.5.5 Fast Termination Cycles
Two clock cycle transfers are supported on the MCF5271 bus. In most cases, this is impractical to
use in a system because the termination must take place in the same half-clock during which TS
is asserted. As this is atypical, it is not referred to as the zero-wait-state case but is called the
fast-termination case. Fast termination cycles occur when the external device or memory asserts
TA less than one clock after TS is asserted. This means that the MCF5271 samples TA on the rising
