Write Protection
array and Status Register are inhibited. WP going low while
CS is still low will interrupt a write operation. If the internal
write cycle has already been initiated, WP going low will
have no effect on any write operation to the Status Register
or memory array. The WP input timing is shown in Figure 8.
When WP input is low all write operations to the memory
