*Notes:
1) VO is referenced to both VDD and temperature. See table on page 6 for exact value(s).
2) “/CS1” & “/CS2” tie to the separate /CS pins on the Master & Slave SED 1520 to be used as the Controller select.
The “E” (/WR) line cannot be used as a “E” line in a 6800 implementation since it is common to both controllers.
3) This module can only use the 8080 style interface, and it is set by the state of the reset line.
Reset occurs when reset line transitions High to Low.
Reset line MUST be left in “Low” signal level condition during normal module operation
4) If /CS1 & /CS2 are both active (high), and /RD line is set to Read (low), damage can occur to module due to bus
contention causing serious over-current conditions.
5) External 2KHz clock must be supplied – see SED-1520 data sheet for clock signal requirements
