PIC16F913/914/916/917/946
16.6
If
programmed, the on-chip program memory can be
read out using ICSP for verification purposes.
16.7
Four memory locations (2000h-2003h) are designated
as ID locations where the user can store checksum or
other code identification numbers. These locations are
not accessible during normal execution, but are
readable and writable during Program/Verify mode.
Only the Least Significant 7 bits of the ID locations are
used.
16.8
The PIC16F91X/946 microcontrollers can be serially
programmed while in the end application circuit. This is
simply done with two lines for clock and data and three
other lines for:
• power
• ground
• programming voltage
This allows customers to manufacture boards with
unprogrammed devices and then program the
microcontroller just before shipping the product. This
also allows the most recent firmware or a custom
firmware to be programmed.
The device is placed into a Program/Verify mode by
holding
RB6/ICSPCLK/ICDCK/SEG14 pins low, while raising
the MCLR (V
“PIC16F91X/946 Memory Programming Specification”
(DS41244) for more information. RB7 becomes the
programming data and the RB6 becomes the
programming clock. Both RB7 and RB6 are Schmitt
Trigger inputs in this mode.
After Reset, to place the device into Program/Verify
mode, the Program Counter (PC) is at location 0000h. A
6-bit command is then supplied to the device. Depending
on the command, 14 bits of program data are then
supplied to or from the device, depending on whether the
command was a load or a read. For complete details of
serial programming, please refer to the “PIC16F91X/946
Memory Programming Specification” (DS41244).
A typical In-Circuit Serial Programming connection is
shown in Figure 16-11.
