 round this limitation. This is because the processor stores float values in a machine word; values can be shared
 between the ISR and main program code via an array of floats.
 
+Using micropython.schedule
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This function enables an ISR to schedule a callback for execution "very soon". The callback is queued for
+execution which will take place at a time when the heap is not locked. Hence it can create Python objects
+and use floats. The callback is also guaranteed to run at a time when the main program has completed any
+update of Python objects, so the callback will not encounter partially updated objects.
+
+Typical usage is to handle sensor hardware. The ISR acquires data from the hardware and enables it to
+issue a further interrupt. It then schedules a callback to process the data.
+
+Scheduled callbacks should comply with the principles of interrupt handler design outlined below. This is to
+avoid problems resulting from I/O activity and the modification of shared data which can arise in any code
+which pre-empts the main program loop.
+
+Execution time needs to be considered in relation to the frequency with which interrupts can occur. If an
+interrupt occurs while the previous callback is executing, a further instance of the callback will be queued
+for execution; this will run after the current instance has completed. A sustained high interrupt repetition
+rate therefore carries a risk of unconstrained queue growth and eventual failure with a ``RuntimeError``.
