DEVICE OPERATION
1. Before a command is issued, status register should be checked to ensure device is ready for the intended operation.
2. When incorrect command is inputted to this LSI, this LSI becomes standby mode and keeps the standby mode until
3. When correct command is inputted to this LSI, this LSI becomes active mode and keeps the active mode until next
4. Input data is latched on the rising edge of Serial Clock(SCLK) and data shifts out on the falling edge of SCLK. The
5. For the following instructions: RDID, RDSR, READ, FAST_READ, RES, and REMS-the shifted-in instruction sequence
6. During the progress of Write Status Register, Program, Erase operation, to access the memory array is neglected and
Note:
CPOL indicates clock polarity of SPI master, CPOL=1 for SCLK high while idle, CPOL=0 for SCLK low while not
transmitting. CPHA indicates clock phase. The combination of CPOL bit and CPHA bit decides which SPI mode is
supported.

is followed by a data-out sequence. After any bit of data being shifted out, the CS# can be high. For the following
instructions: WREN, WRDI, WRSR, Parallel Mode, SE, CE, PP, EN4K, EX4K, RDP and DP the CS# must go high
