Trvalo to asi pol minuty najst:

An ongoing Flash memory operation will not block the CPU as long as the CPU
does not
access the Flash memory.
On the contrary, during a program/erase operation to the Flash memory, any
attempt to read
the Flash memory will stall the bus. The read operation will proceed
correctly once the
program/erase operation has completed. This means that code or data fetches
cannot be
made while a program/erase operation is ongoing.

Dalej, podla datasheetu pre '030', programovaci cas pre 16 bitov (co je
jedina moznost) je typ. 53.5us, max. bohuzial neuvedeny; na druhej strane
maze sa po 1kB strankach ale to trva typ. 30ms.
