MOTOROLA
MC68340 USER’S MANUAL
3- 33
EXAMPLE B: A system uses error detection and correction on RAM contents. The
designer may:
1. Delay
DSACK
≈ until data is verified and assert BERR and HALT simultaneously to
indicate to the MC68340 to automatically retry the error cycle (case 5), or if data is
valid, assert
DSACK
≈ (case 1).
2. Delay
DSACK
≈ until data is verified and assert BERR with or without DSACK≈ if
data is in error (case 3). This initiates exception processing for software handling of
the condition.
3. Return
DSACK
≈ prior to data verification; if data is invalid, BERR is asserted on the
next clock cycle (case 4). This initiates exception processing for software handling of
the condition.
4. Return
DSACK
≈ prior to data verification; if data is invalid, assert BERR and HALT
on the next clock cycle (case 6). The memory controller can then correct the RAM
prior to or during the automatic retry.

NOTES:
N — Number of the current even bus state (e.g., S2, S4, etc.)
A — Signal is asserted in this bus state
NA — Signal is not asserted in this state
X — Don't care
S — Signal was asserted in previous state and remains asserted in this state
