I think the biggest problem with this function is it is write-read. But
our nodes are either read or write, never both.
What is you application for this? It may help to decide how to implement

That depends on how long your pulses have to be. If I read the datasheet
correctly, tpulse is fixed so using an external hardware which generates
the neccessary pulse would to the trick, too.
