READ OPERATIONS
Read from Memory Array
To read from memory, the host sends a READ
instruction followed by a 8-bit address (for the
CAT25040, bit 3 of the read instruction opcode
contains A8 address bit).
After
receiving
the
last
address
bit,
the
CAT25010/20/40 will respond by shifting out data on
the SO pin (as shown in Figure 8). Sequentially stored
data can be read out by simply continuing to run the
clock. The internal address pointer is automatically
incremented to the next higher address as data is
shifted out. After reaching the highest memory
address, the address counter “rolls over” to the lowest
memory address, and the read cycle can be continued
indefinitely. The read operation is terminated by taking
CS
high.
Read Status Register
To read the status register, the host simply sends a
RDSR command. After receiving the last bit of the
command, the CAT25010/20/40 will shift out the
contents of the status register on the SO pin
(Figure 9). The status register may be read at any
time, including during an internal write cycle.
