11.4.1
Flash memory write and erase operations are
controlled by the NVMCON register. Programming is
performed by setting NVMCON to select the type of
erase operation
(Table
programming and initiating the programming by setting
the WR control bit, NVMCON<15>.
In ICSP mode, all programming operations are
externally timed. An external 2 ms delay must be used
between setting the WR control bit and clearing the WR
control bit to complete the programming operation.

TABLE 11-3:
11.4.2
Writes to the WR bit (NVMCON<15>) are locked to
prevent accidental programming from taking place.
Writing a key sequence to the NVMKEY register
unlocks the WR bit and allows it to be written to. The
unlock sequence is performed as follows:
11.4.3
Once the unlock key sequence has been written to the
NVMKEY register, the WR bit (NVMCON<15>) is used
to start and stop an erase or write cycle. Setting the WR
bit initiates the programming cycle. Clearing the WR bit
terminates the programming cycle.
All erase and write cycles must be externally timed. An
external delay must be used between setting and
clearing the WR bit. Starting and stopping a
programming cycle is performed as follows:
11.5
The procedure for erasing program memory (all code
memory, data memory, executive memory and code-
protect bits) consists of setting NVMCON to 0x407F,
unlocking NVMCON for erasing and then executing the
programming cycle. This method of bulk erasing pro-
gram memory only works for systems where V
between 4.5 volts and 5.5 volts. The method for erasing
program memory for systems with a lower V
volts-4.5 volts) is described in
