For the page write operation (byte or page write) to be
completed, CS can only be brought HIGH after bit 0 of
the last data byte to be written is clocked in. If it is
brought HIGH at any other time, the write operation will
not be completed (Figure 4).
To write to the status register, the WRSR instruction is
followed by the data to be written (Figure 5). Data bits
0 and 1 must be “0” .
While the write is in progress following a status register or
EEPROM sequence, the status register may be read to
check the WIP bit. During this time the WIP bit will be high.
OPERATIONAL NOTES
The device powers-up in the following state:
– The device is in the low power standby state.
– A HIGH to LOW transition on CS is required to enter
an active state and receive an instruction.
– SO pin is high impedance.
– The write enable latch is reset.
– The flag bit is reset.
– Reset signal is active for t
PURST
.
Data Protection
The following circuitry has been included to prevent
inadvertent writes:
– A WREN instruction must be issued to set the write
enable latch.
– CS must come HIGH at the proper clock count in
order to start a nonvolatile write cycle.
