Revision:
3:8e9b9f5818aa
Parent:
0:e4a10ed6eb92 
Removed Bulk Erasing, instead a small number of bytes are sampled from each and every page to determine if sector is "dirty", if so sector is erased

Prevents device from sleeping when the firmware detects a series of binary flash page RPC transfers, this increases flash page transfers by %450

  when 200mS elapse with the last flash page transfer, normal sleep behaviour is resumed
