Description
Notes: *1 Preprogramming (setting erase block data to all “0”) is not necessary.
*2 Verify data is read in 32-bit (longword) units.
*3 Set only one bit in EBR1(2). More than one bit cannot be set.
*4 Erasing is performed in block units. To erase a number of blocks, each block must be erased in turn.
*5 Make sure to set the wait times and repetitions as specified. Erasing may not complete correctly if values other
than the specified ones are used.
