Asynchronous Write - UB, LB Controlled (OE =

IH
or
V
IL
, ZZ =
V
IH
)
The programming of control register in asynchronous mode is performed in the similar manner as asynchronous
write except ZZ being held low during the operation. Note that ZZ has to meet set-up time (
t
ZZWE
) and hold time
(
t
WEZZ
)of valid state (= Low) in reference to WE falling and rising edge, respectively. CS1 should toggle at the end
of the operation to get ready for following access.
