EECLK period ECLK 1.0 µs
EESD input setup time EISU 100 ns
EESD input hold time EIH 100 ns
EESD output setup time* EOSU 500 ns

asserted to EECLK positive edge ECSS 500 ns
EESD tristated before last falling EECLK edge during read
cycle. Last positive half of EECLK cycle is extended to pro-
vide both 500 ns minimum EOH and 100 ns EESD before
EECLK falling edge.
EOZ 100 ns
