Memory is erased by using an ERASEB, ERASED or
ERASEP command, as detailed in
“Command
erased by row using ERASEP. Data EEPROM can be
erased by row using ERASED. When memory is erased,
the affected memory locations are set to ‘1’s.
ERASEB
Performing a Chip Erase with the ERASEB command
clears all code memory, data EEPROM and code
protection registers. Alternatively, ERASEB can be used
to selectively erase either all code memory or data
EEPROM. Erase options are summarized in
TABLE 6-1:
6.2
Instead
programming, 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
and data EEPROM using ERASEP and ERASED,
respectively. You can then reprogram the modified
rows with the PROGP and PROGD command pairs. In
these cases, when code memory is programmed,
single-panel programming must be specified in the
PROGP command.
For modification of Advanced Code Protection bits for
a particular segment, the entire chip must first be
erased with the ERASEB command. Alternatively, on
devices that support Advanced Security, individual
segments (code and/or data EEPROM) may be
erased, by suitably changing the MS (Memory Select)

The READD command reads the data EEPROM,
Configuration bits and device ID of the device. This
command only returns 16-bit data and operates on
16-bit registers. READD can be used to return the
entire contents of data EEPROM.
The READP command reads the code memory of the
device. This command only returns 24-bit data packed
as described in
READP can be used to read up to 32K instruction words
of code memory.

At times, it may be necessary to determine the version
of programming executive stored in executive memory.
The QVER command performs this function. See
Section 8.5.11 “QVER Command”
about this command.
6.5
To allow portability of code, the programmer must read
the data EEPROM information from the hexadecimal
file. If data EEPROM information is not present, a
simple warning message should be issued by the
programmer. Similarly, when saving a hexadecimal file,
all data EEPROM information must be included. An
option to not include the data EEPROM information can
be provided.
Microchip Technology Inc. believes that this feature is
important for the benefit of the end customer.
