Как это нету? Всё там есть PAGE ERASE: The optional Page Erase command can be used to individually erase
any page in the main memory array allowing the Buffer to Main Memory Page Program
without Built-in Erase command to be utilized at a later time. To perform a Page Erase,
an opcode of 81H must be loaded into the device, followed by four reserved bits,
11 address bits (PA10 - PA0), and nine don’t care bits. The 11 address bits are used to
specify which page of the memory array is to be erased. When a low-to-high transition
occurs on the CS pin, the part will erase the selected page to 1s. The erase operation is
internally self-timed and should take place in a maximum time of tPE. During this time,
the status register will indicate that the part is busy.
