(Q = 0) will be returned if S is driven high, and the
ST93C46will ignoreanydataon thebus.Whenthe
write cycle is completed, theReady signal (Q = 1)
will indicate (if S is driven high) that the ST93C46
is ready to receivea new instruction.
The Writeinstruction includesan automaticErase
cycle beforewriting the data, it is thereforeunnec-
essary to execute an Erase instruction before a
Write instruction execution.
EraseAll
The Erase All instruction (ERAL) erases the whole
memory (all memory bits are set to ”1”).A dummy
addressis input duringthe instructiontransfer and
the erase is made in the sameway as the ERASE
instructionabove.IftheST93C46 isstillperforming
the write cycle, the Busy signal (Q = 0) will be
returnedif S is driven high, and the ST93C46will
ignore any data on the bus. When the write cycle
is completed,the Readysignal (Q = 1)will indicate
(if S is driven high) that the ST93C46 is ready to
receive a new instruction.
Write All
For correct operation,an ERAL instructionshould
be executedbefore the WRALinstruction.
The Write All instruction (WRAL) writes the Data
Input byte or word to all the addresses of the
memory. In the WRAL instruction, NO automatic
erase is made so all bytes/words must be erased
beforetheWRALinstruction. IftheST93C46isstill
performing the write cycle, the Busy signal (Q = 0)

will ignore any data on the bus. When the write
cycle is completed, the Ready signal (Q = 1) will
indicate (if S is driven high) that the ST93C46 is
ready to receive a newinstruction.
