Read Status Register (RDSR)
The RDSR instruction provides read
access
to
the
status
register.
The
BUSY/RDY and WREN statuses of the
device can also be determined by this
instruction. In addition, the Block Write
Protection bits indicate the extent of
protection employed. In order to determine
the status of the device, the value of the
/RDY bit can be continuously polled before
sending any write instruction.
Write Status Register (WRSR)
The WRSR instruction enables the user to
select one of four levels of protection. The
SA25C512 is divided into four array
segments. The top quarter, top half or all of
the memory segments can be protected
(for more details, refer to Table 7). The
data within a selected segment is therefore
read-only.

The WRSR instruction (as shown in
Table 8) also allows the user to enable or
disable the WPb pin via the WPBEN bit.
Hardware write protection is enabled when
the WPb pin is low and the WPBEN bit is
1, and disabled when either the WP pin is
high or the WPBEN bit is 0. When the
device is hardware write protected, writes
to the status register are disabled.
NOTE:
When the WPBEN bit is hardware write
protected, it cannot be changed back
to 0 as long as the WPb pin is held low.

Read Sequence (READ)
Reading the SA25C512 via the SO pin
requires the following sequence (for more
details, see Table 9, page 12):
1. After the CSb line is pulled low to select
the device, the READ opcode is
transmitted via the SI line, followed by
the byte address to be read. Upon
completion, any data on the SI line is
ignored.
2. The data (D7-D0) at the specified
address is then shifted out onto the SO
line.
If only one byte is to be read, the CSb line
should be driven high after the data comes
out.
The
READ
sequence
can
be
continued,
as
the
byte
address
is
automatically
incremented
and
data
continues to shift out. When the highest
address is reached, the address counter
rolls over to the lowest address, enabling
the entire memory to be read in one
continuous READ cycle.
