Lpc2000

Hi Bob,

I would presume that a page with some programmed zero bits, but most still
erased
bytes at 0xff can still be program those 0xFF bytes to another value ?
(ie without an erase cycle)
Otherwise that'd be kind of a problem, having to erase a page each time you
want to store a
couple of bytes ???

Best regards,
Kris
