3.2.3
The program memory may also be written one word at
a time to allow compatibility with other 8-pin and 14-pin
Flash PIC
(>0x2000) and data memory must be written one word
(or byte) at a time.
The sequence for programming one word of program
memory at a time is as follows:
1.
2.
3.

As a result, the write latches are not reset when
programming these locations and must be reset by the
programmer. This can be done in two ways, either
loading all eight latches with ‘1’s or by exiting Program/
Verify mode.
The sequence for manually resetting the write latches
is as follows:

Issue an Increment Address command.
Repeat this sequence three times on the
PIC16F883/884 and seven times on the
PIC16F886/887 to reset all write latches.

3.2.5
The PIC16F88X will erase different memory locations
depending on the Program Counter (PC), CP and CPD
values, and which erase command is executed. The
following sequences can be used to erase noted
memory locations. In each sequence, the data memory
will be erased if the CPD bit in the Configuration Word
is programmed (clear).
To erase the program memory and Configuration
Words (0x2007-0x2008), the following sequence must
be performed. Note the Calibration Word (0x2009) and
user ID (0x2000-0x2003) will not be erased.
1.

To erase the user ID (0x2000-0x2003), Configuration
Words (0x2007-0x2008) and program memory, use the
following sequence.

To erase the data memory, use the following sequence:
