7.33. Read Security Registers (48H)
The Read Security Registers command is similar to Fast Read command. The command i 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 higher 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.
