M95M02 is no working?

Working way: W and Hold is high, Other SPI BUS.

First we send "RDSR" Command but MISO is low like no working, so I try send "WREN" and "WRSR"but is no working.

​Hello,

Even if MISO is low after RDSR doesn't mean it doesn't work. Status register content = 0x00 will give you MISO = low.

Please try  WREN + RSDR. You should have WEL bit = 1

(confirm your hexa command)

I find the answer.

your datasheet :

1.Before accepting the execution of the Write and Write Status register instructions, the

device checks whether the number of clock pulses comprised in the instructions is a

multiple of eight​.

so: send“RSDR"+"0xff".
