+  The IO timer runs every 1ms or at 1Khz. The standard flash chip can write roughly 130Kb/s
   so there is little point in trying to write more than 130 bytes - or 1 page (256 bytes).
   The W25Q128FV datasheet gives tpp as typically 0.7ms yielding an absolute maximum rate of
   365Kb/s or just over a page per cycle.
