WRITE PROTECT: Erase blocks can be locked by writing a non-volatile lock-bit for
each block. When WP is low, those locked blocks as reflected by the Block-Lock Status
bits (BSR.6), are protected from inadvertent Data Writes or Erases. When WP is high,
all blocks can be Written or Erased regardless of the state of the lock-bits. The WP
input buffer is disabled when RP
BYTE ENABLE: BYTE low places device in x8 mode. All data is then input or output
on DQ
byte. BYTE high places the device in x16 mode, and turns off the A
