Erase
The Erase instruction (ERASE) programs the ad-
dressed memory byteor word bitsto ’1’. Oncethe
addressiscorrectlydecoded,thefallingedgeofthe
Chip Select input (S) starts a self-timed program-
ming cycle.
If the ST93C46 is still performing the write cycle,
the Busysignal (Q= 0)will bereturnedif Sisdriven
high, and the ST93C46will ignoreany dataon the
bus. When thewrite cycle iscompleted,the Ready
signal (Q = 1) will indicate (if S is driven high) that
the ST93C46is ready to receive a new instruction.
Write
The Write instruction (WRITE) is followed by the
addressandthe8or16databitsto bewritten. Data
input is sampled on the Low to High transition of
the clock.After thelast databit has beensampled,
Chip Select (S) must be brought Low before the
next rising edge of the clock(C), in order to start
the self-timed programming cycle. If the ST93C46
is still performing the write cycle, the Busy signal

2. Xn: n = 3 for x16 org. and 4 for x8 org.
