Warning: the number of write cycles of the nonvolatile memory of the module is limited. When this
limit is reached, nothing guaranties that the saving process is performed correctly. This limit, linked to
the technology employed by the module micro-processor, is located at about 100000 cycles. In short,
you can use the
YModule.saveToFlash()
function only 100000 times in the life of the module.
Make sure you do not call this function within a loop.
