3.4
3.4.1
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 3-2) or write operation (Table 3-3) and initiating
the programming by setting the WR control bit
(NVMCON<15>).
In ICSP mode, all programming operations are
self-timed. There is an internal delay between the user
setting the WR control bit and the automatic clearing of
the WR control bit when the programming operation
is complete. Please refer to Section 7.0 “AC/DC
Characteristics and Timing Requirements” for
information about the delays associated with various
programming operations.

TABLE 3-3:
3.4.2
The WR bit (NVMCON<15>) is used to start an erase or
write cycle. Setting the WR bit initiates the programming
cycle.
All erase and write cycles are self-timed. The WR bit
should be polled to determine if the erase or write cycle
has been completed. Starting a programming cycle is
performed as follows:

The procedure for erasing program memory (all of code
memory, data memory, executive memory and
code-protect bits) consists of setting NVMCON to
404Fh and executing the programming cycle.
A Chip Erase can erase all of user memory or all of both
the user and configuration memory. A table write
instruction should be executed prior to performing the
Chip Erase to select which sections are erased.
When this table write instruction is executed:
• If the TBLPAG register points to user space (is
• If TBLPAG points to configuration space (is
Figure 3-5 shows the ICSP programming process for
performing a Chip Erase. This process includes the
ICSP command code, which must be transmitted (for
each instruction), Least Significant bit first, using the
PGCx and PGDx pins (see Figure 3-2).

greater than or equal to 0x80), the Chip Erase will
erase both user and configuration memory.
If configuration memory is erased, the internal
oscillator Calibration Word, located at 0x807FE,
will be erased. This location should be stored prior
to performing a whole Chip Erase and restored
afterward to prevent internal oscillators from
becoming uncalibrated.
Note:
Erasing Program Memory
Program memory must be erased before
writing any data to program memory.
