values\n# in non-volatile memory. I&#39;m investigating the cause of this instability\n# and looking for a solution. \n\n# Note that writing to volatile memory is working as expected.\n\n# 2023-05-28\n# The unstable behavior observed is a result of the write operations\n# to non-volatile memory taking longer than expected,\n# leading to data loss when consecutive write commands are executed.\n# To achieve stability, I have introduced a waiting time. Currently,\n# I have set it to 100 msec temporarily, but it seems that a waiting\n# time of 10 msec is insufficient.\n\n# Unfortunately, I could not find this information in the datasheet.\n# It&#39;s possible that I may have overlooked it.\n\n# 2023-05-29\n# Non-volatile memory write busy time is 12 ms.
