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.

Enable Reset (66H) and Reset (99H)

If the Reset command is accepted, any on-going internal operation will be terminated and the device will return to its

default power-on state and lose all the current volatile settings, such as Volatile Status Register bits, Write Enable Latch

status (WEL), Program/Erase Suspend status, Read Parameter setting (P7-P0), Continuous Read Mode bit setting

(M7-M0) and Wrap Bit Setting (W6-W4).

The

“Reset (99H)” command sequence as follow: CS# goes low  Sending Enable Reset command  CS# goes

high  CS# goes low  Sending Reset command  CS# goes high. Once the Reset command is accepted by the device,

the device will take approximately tRST / tRST_E to reset. During this period, no command will be accepted. Data corruption

may happen if there is an on-going or suspended internal Erase or Program operation when Reset command sequence is

accepted by the device. It is recommended to check the BUSY bit and the SUS bit in Status Register before issuing the

Reset command sequence.
