VER 1.1

Read Security Registers (48H)

The Read Security Registers command is similar to Fast Read command. The command is followed by a

3- byte address (A23-A0) and a dummy byte, each bit being latched-in during the rising edge of SCLK.

Then the memory content, at that address, is shifted out on SO, each bit being shifted out, at a Max

frequency fC, during the falling edge of SCLK. The first byte addressed can be at any location. The

address is automatically incremented to the next address after each byte of data is shifted out. Once the

A9-A0 address reaches the last byte of the register (Byte 3FFH), it will reset to 000H, the command is

completed by driving CS# high.
