FUNCTIONAL DESCRIPTION
DELAY TIME
EASY MODE
The Easy Mode is activated when the EASY/(/MCU) Pin is in HIGH State. Under the Easy Mode;
namely – DL1/REQ, DL2/CLK, DL3/DIN, and DL4/IDS are all used as inputs for Delay Time Data (DL1
~ DL4).
The Delay Pins: namely -- DL1~DL4 determine the amount of time the memory-stored signal would be
stored in the 48 K-bit memory (delay time). The following table gives the various Delay Time with
reference to the Pins DL1 ~ DL4.
