Question:
What about the basic terms (verify, ready/busy function)
Answer:
Verify, ready/busy (R/B) function
This is a function to find out about an actual write operation (time). There are two methods, a
“monitoring method based on the output condition of the DO pin” and a “method for monitoring the
output condition of the Ready/Busy pin.” This function eliminates the need to wait 10 ms for writing to be
completed, thereby minimizing the write time according to the performance of the IC (performance
value: 4 ms to 5 ms; 1 ms is ensured for the S-24C series).
