19.
Measured with W (bar) and NE (bar) both returned high, and G (bar) returned low. Address transitions may not occur on
any address pin during this time.
20.
Once t
RC
has been satisfied by NE (bar), G (bar), W (bar) and E (bar) the RECALL cycle is completed automatically. Any
of NE (bar), G (bar) or E (bar) may be used to terminate the RECALL initiation cycle.
