OSC
(drawing not to scale) This delay will not be there for RC osc mode.
GIE = '1' assumed. In this case after wake- up, the processor jumps to the interrupt routine. If GIE = '0', execution will continue in-line.
CLKOUT is not available in these osc modes, but shown here for timing reference.

If the code protection bit(s) have not been pro-
grammed, the on-chip program memory can be read
out for verification purposes.
Program Verification/Code Protection
8.10
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 read-
able and writable during program/verify. It is recom-
mended that only the 4 least significant bits of the ID
location are used.
ID Locations
8.11
PIC16CXX microcontrollers can be serially pro-
grammed while in the end application circuit. This is
simply done with two lines for clock and data, and three
other lines for power, ground, and the 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 firm-
ware to be programmed.
In-Circuit Serial Programming
Note:
Microchip does not recommend code pro-
tecting windowed devices.
The device is placed into a program/verify mode by
holding the RB6 and RB7 pins low while raising the
MCLR (V
PP
) pin from V
IL
to V
IHH
(see programming
specification). RB6 becomes the programming clock
and RB7 becomes the programming data. Both RB6
and RB7 are Schmitt Trigger inputs in this mode.
After reset, to place the device into programming/verify
mode, the program counter (PC) is at location 00h. A 6-
bit command is then supplied to the device. Depending
on the command, 14-bits of program data are then sup-
plied to or from the device, depending if the command
was a load or a read. For complete details of serial pro-
gramming, please refer to the PIC16C6X/7X Program-
ming Specifications (Literature #DS30228).
