A12 08/04/2020 8.12 BLOCK ERASE OPERATION (BER32K:52h, BER64K:D8h) A Block Erase (BER) instruction erases a 32/64Kbyte block. Before the execution of a BER instruction, the Write Enable Latch (WEL) must be set via a Write Enable (WREN) instruction. The WEL is reset automatically after the completion of a block erase operation. The BER instruction code and three address bytes are input via SI. Erase operation will start immediately after the CE# is pulled high, otherwise the BER instruction will not be executed. The internal control logic automatically handles the erase voltage and timing.
