Status Register
The Status Register, as shown in Table 8, contains a
number of status and control bits.
The RDY (Ready) bit indicates whether the device is busy
with a write operation. This bit is automatically set to 1 during
an internal write cycle, and reset to 0 when the device is ready
to accept commands. For the host, this bit is read only.
The WEL (Write Enable Latch) bit is set/reset by the
WREN/WRDI commands. When set to 1, the device is in a
Write Enable state and when set to 0, the device is in a Write
Disable state.
The BP0 and BP1 (Block Protect) bits determine which
blocks are currently write protected. They are set by the user
with the WRSR command and are non−volatile. The user is
allowed to protect a quarter, one half or the entire memory,
by setting these bits according to Table 9. The protected
blocks then become read−only.
The WPEN (Write Protect Enable) bit acts as an enable for
the WP pin. Hardware write protection is enabled when the
WP pin is low and the WPEN bit is 1. This condition
prevents writing to the status register and to the block
protected sections of memory. While hardware write
protection is active, only the non−block protected memory
can be written. Hardware write protection is disabled when
the WP pin is high or the WPEN bit is 0. The WPEN bit, WP
pin and WEL bit combine to either permit or inhibit Write
operations, as detailed in Table 10.
