READ OPERATIONS
Read from Memory Array
To read from memory, the host sends a READ instruction
followed by a 16bit address (see Table 11 for the number
of significant address bits).
After receiving the last address bit, the CAT25128 will
respond by shifting out data on the SO pin (as shown in
Figure 9). 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
CAT25128 will shift out the contents of the status register on
the SO pin (Figure 10). The status register may be read at
any time, including during an internal write cycle. While the
internal write cycle is in progress, the RDSR command will
output the RDY (Ready) bit status only (i.e., data out = FFh).
