PIC16F91X/946
3.1
The PIC16F91X/946 program memory may be written
in three ways. The PIC16F913/914 uses one-word and
four-word writes. The PIC16F916/917/946 uses one-
word, four-word and eight-word writes. The four-word
or eight-word algorithm is used to program the program
memory only. The one-word algorithm can write any
available memory location (i.e., program memory,
configuration memory and data memory).
After writing the array, the PC may be reset and read
back to verify the write. It is not possible to verify
immediately following the write because the PC can
only increment, not decrement.
A device Reset will clear the PC and set the address to
‘0’. The Increment Address command will increment
the PC. The Load Configuration command will set the
PC to 0x2000. The available commands are shown in
Table 3-1.
3.1.1
Only the program memory on PIC16F916/917/946 can
be written using this algorithm. Data and configuration
memory
programming algorithm (Section 3.1.3 “One-Word
Programming”).
This algorithm writes eight sequential addresses in
program memory. The eight addresses must point to an
eight-word block with addresses modulo 8 of 0, 1, 2, 3,
4, 5, 6 and 7. For example, programming address 8
through 15 can be programmed together. Program-
ming addresses 2 through 9 will create an unexpected
result.
The sequence for programming eight words of program
memory at a time is as follows:
1.

3.1.2
Four-word programming can be used on all devices in
the PIC16F91X/946 family. Only the program memory
can be written using this algorithm. Data and configura-
tion memory (>0x2000) must use the one-word
programming algorithm (Section 3.1.3 “One-Word
Programming”).
This algorithm writes four sequential addresses in
program memory. The four addresses must point to a
four-word block with addresses modulo 4 of 0, 1, 2 and
3. For example, programming address 4 through 7 can
be programmed together. Programming addresses 2
through 5 will create an unexpected result.
The sequence for programming four words of program
memory at a time is as follows:
