MC68340 USER’S MANUAL
3- 15
If a system asserts
DSACK
≈ for the required window around the falling edge of S2 and
obeys the proper bus protocol by maintaining
DSACK
≈ (and/or BERR/HALT) until and
throughout the clock edge that negates
AS (with the appropriate asynchronous input hold
time), no wait states are inserted. The bus cycle runs at its maximum speed for bus cycles
terminated with
DSACK
≈ (three clocks per cycle). When BERR (or BERR and HALT) is
asserted after
DSACK
≈, BERR (and HALT) must meet the appropriate setup time prior to
the falling clock edge one clock cycle after
DSACK
≈ is recognized. This setup time is
critical, and the MC68340 may exhibit erratic behavior if it is violated. When operating
synchronously, the data-in setup and hold times for synchronous cycles may be used
instead of the timing requirements for data relative to
DS.
3.2.6 Fast Termination Cycles
With an external device that has a fast access time, the chip select circuit fast termination
enable (FTE) can provide a two-clock external bus transfer. Since the chip select circuits
are driven from the system clock, the bus cycle termination is inherently synchronized with
the system clock. Refer to Section 4 System Integration Module for more information on
chip selects.When fast termination is selected, the DD bits of the corresponding address
mask register are overridden. Fast termination can only be used with zero wait states. To
use the fast termination option, an external device should be fast enough to have data
ready, within the specified setup time, by the falling edge of S4. Figure 3-6 shows the
DSACK
≈ timing for a read with two wait states, followed by a fast termination read and
write. When using the fast termination option,
DS is asserted only in a read cycle, not in a
write cycle.
