2. Write (WRITE, ERASE)
There are two write instructions, WRITE, ERASE. Each automatically begins writing to the non-volatile memory when
CS goes low at the completion of the specified clock input.
The write operation is completed in 10 ms (t
PR
Max.), and the typical write period is less than 5 ms. In the S-29LXX1A
Series, it is easy to VERIFY the completion of the write operation in order to minimize the write cycle by setting CS to
high and checking the DO pin, which is low during the write operation and high after its completion. This VERIFY
procedure can be executed over and over again. There are two methods to detect a change in the DO output. One is
to detect a change from low to high setting CS to high, and the other is to detect a change from low to high as a result
of repetitous operations of returning the CS to low after setting CS to high and checking the DO output.
Because all SK and DI inputs are ignored during the write operation, any input of instruction will also be disregarded.
When DO outputs high after completion of the write operation or if it is in the high-impedence state (Hi-Z), the input of
instructions is available. Even if the DO pin remains high, it will enter the high-impedence state upon the recognition
of a high of DI (start-bit) attached to the rising edge of an SK pulse.
DI input should be low during the VERIFY procedure.
