WRITE PROTECT: The write protect pin (WP) will allow normal read/write operations when held high. When the
WP pin is brought low and WPEN bit is “1”, all write operations to the status register are inhibited. WP going low
while CS is still low will interrupt a write to the status register. If the internal write cycle has already been initiated,
WP going low will have no effect on any write operation to the status register. The WP pin function is blocked when
the WPEN bit in the status register is “0”. This will allow the user to install the Atmel ? AT25128B/256B in a system
with the WP pin tied to ground and still be able to write to the status register. All WP pin functions are enabled
when the WPEN bit is set to “1”.
