Question:
False-writes in S-93C, S-29 series: inadvertent activation of CS (malfunction)
Answer:
Inadvertent writing in the S-29 series
In the S-29 series, when a CS input is inadvertently activated during a write command, undefined data
may be written. Relevant timings are shown below.
A command is composed of the following: “start bit + two command bits + address + (data).”
The figure below shows the timings in which commands are set (In the figure, the portion denotes the
rising edge of SK.)
In the case of a write command, after a final address has been input and while 16-bit data is being input,
undefined data is written when the CS input is changed from H to L.
