WRITE (WRITE, ERASE, WRAL, ERAL)
There are four write instructions, WRITE, ERASE, WRAL, and ERAL. 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 (tPR Max.), and the typical write period is less than 5 ms. In the S-29XX0A
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.
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. (see Figure 3).
DI input should be low during the VERIFY procedure.
