carried out by means of RES input. The state of ports with multiplexed address functions and bus control output
pins (AS, RD, HWR, LWR) will change during this switchover interval (the interval during which the RES pin
input is low), and therefore these pins should not be used as output signals during this time.
ns is necessary with respect to RES clearance timing.
