2. Timings for Reading out Status Data

Status data that can be read includes two types, the status register (refer to the section 1.7, RDSTAT Command)

and the memory address counter (refer to the section 1.6, RDADR Command).

Timings for reading status data are shown in the charts below. After “L” input to the CS pin, input the RDSTAT

command to read status data. While the CS pin being held “L”, status data is output to the DO pin in serial

sequence starting with the MSB, in synchronization with the 4th pulse SCK’s falling edge following the command

input. After reading status data, the DO pin returns to “Hi-Z” status regardless the number of SCK pulse, when the

CS pin is brought to “H” level.
