DESCRIPTION
The X88064 is a high speed byte wide microperipheral
device with eight 1K byte blocks of E
directly connected to industry standard high performance
microprocessors. This peripheral provides two levels of
memory write control, the standard Software Data Pro-
gram (SDP) control and Block Lock.

PROM and can be
Block Lock provides a higher level of memory write con-
trol above SDP This allows the software developer to
partition any or all of the eight 1K byte blocks as In-Circuit
Programmable ROM (ICPROM). Once locked, a block of
memory must first be unlocked before being written. Not
even a write operation using the SDP sequence will
change the contents of a locked block. Since a distinct, 6
byte, software command sequence locks and unlocks
the memory, the software developer has complete con-
trol of the memory contents.
