Fig.11 READ STATUS REGISTER CYCLE TIMING
The data stored in the status register is clocked out after “Read Status Register” instruction
is received.
After CS goes low, Op.code of “Read Status Register” need to sent.
The data stored in the status register is clocked out of the device on the falling edge of 7th
clock. Bit6, Bit5 and Bit4 in the status register are read as 0.
This device has the auto-increment feature as well as “Read” that outputs the 8bits of the
same data following it to keep SCK clocking.
It is possible to see ready and busy state by executing this command during tE/W.
