6.1
Memory is erased by using an ERASEB or ERASEP
command, as detailed in
Descriptions”. Code memory can be erased by row
using the ERASEP command. When memory is erased,
the affected memory locations are set to ‘1’s.
The ERASEB command provides several Bulk Erase
options. Performing a Chip Erase with the ERASEB
command clears all code memory and code protection
registers. Alternatively, the ERASEB command can be
used to selectively erase individual program memory
segments.Table 6-1
TABLE 6-1:
6.2
Instead of bulk-erasing the device before starting to
program, it is possible that you may want to modify only
a section of an already programmed device. In this
situation, Chip Erase is not a realistic option.
Instead, you can erase selective rows of code memory
using the ERASEP command. You can then reprogram
the modified rows with the PROGP command pairs.
In these cases, when code memory is programmed,
single-panel programming must be specified in the
PROGP command.
For modification of code-protect bits, the entire chip
must first be erased with the ERASEB command. The
code-protect bits can be reprogrammed using the
PROGC command.

FEATURES
Erasing Memory
Modifying Memory
The system operation Configuration
registers and device ID registers are not
erasable.
ERASEP cannot be used to erase
code-protect Configuration bits. These bits
must be erased using ERASEB.
If read or write code protection is enabled,
no modifications can be made to any
region of code memory until code
protection is disabled. Code protection
can only be disabled by performing a Chip
Erase with the ERASEB command.

6.3
The READD command reads the Configuration bits and
device ID of the device. This command only returns
16-bit data and operates on 16-bit registers.
The READP command reads the code memory of the
device. This command only returns 24-bit data packed
as described in
The READP command can be used to read up to 32K
instruction words of code memory (only 4K instruction
words are present on the dsPIC30F SMPS devices).

At times, it may be necessary to determine the version
of programming executive stored in executive memory.
The QVER command performs this function. See
