READ OPERATIONS
Read from Memory Array
To read from memory, the host sends a READ
instruction followed by an 8-bit address (for the
CAT15008, bit 3 of the Read instruction opcode
contains address bit A8).
After receiving the last address bit, the CAT15002/04
will respond by shifting out data on the SO pin (as
shown in Figure 10). 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 CAT15002/04 will shift out the contents
of the status register on the SO pin (Figure 11). The
status register may be read at any time, including
during an internal write cycle.
