the write enable latch (WEL) must first be set by issuing
the
Once the write enable latch is set, the user may pro-
ceed with issuing a ERAL instruction (including the
header and device address bytes). Immediately after
the NoMAK bit has been transmitted by the master, the
internal write cycle is initiated, during which time all
words of the memory array are written to ‘0x00’.
