Bus operations
M50FW040
18/53
3.1.3
Bus Abort
The Bus Abort operation can be used to immediately abort the current bus operation. A Bus
Abort occurs when FWH4 is driven Low, V
IL
, during the bus operation; the memory will tri-
state the Input/Output Communication pins, FWH0-FWH3.
Note that, during a Bus Write operation, the Command Interface starts executing the
command as soon as the data is fully received; a Bus Abort during the final TAR cycles is
not guaranteed to abort the command; the bus, however, will be released immediately.
3.1.4
Standby
When FWH4 is High, V
IH
, the memory is put into Standby mode where FWH0-FWH3 are
put into a high-impedance state and the Supply Current is reduced to the Standby level,
I
CC1
.
3.1.5
Reset
During Reset mode all internal circuits are switched off, the memory is deselected and the
outputs are put in high-impedance. The memory is in Reset mode when Interface Reset, RP,
or CPU Reset, INIT, is Low, V
IL
. RP or INIT must be held Low, V
IL
, for t
PLPH
. The memory
resets to Read mode upon return from Reset mode and the Lock Registers return to their
default states regardless of their state before Reset, see
Table 10
If RP or INIT goes Low,
V
IL
, during a Program or Erase operation, the operation is aborted and the memory cells
affected no longer contain valid data; the memory can take up to t
PLRH
to abort a Program
or Erase operation.
3.1.6
Block Protection
Block Protection can be forced using the signals Top Block Lock, TBL, and Write Protect,
WP, regardless of the state of the Lock Registers.
