Protect modes
There are three protect modes, hardware, software, and error protect, which allow protected
status to be designated for flash memory program/erase/verify operations.
Writer mode
Flash memory can be programmed/erased in writer mode, using a PROM programmer, as well
as in on-board programming mode.

mask ROM, and ROMless versions, so an undefined value will be returned if they
are read, and it is not possible to write to these registers.
