PROMs: What is the unprogrammed/default state of each byte address in an XC1700 PROM?
Problem Description:
Urgency: Standard
General Description
The question often arises as to what the unprogrammed
state of an XC1700/D/L/E PROM is.
Solution 1:
The unprogrammed state of each byte address is 'FFH', or in
other words, each bit is programmed to a '1'. This includes
the byte addresses that control the PROM programmable reset
polarity, which causes the polarity to default to active
HIGH reset.
