Note 1: XT, HS or LP oscillator mode assumed.
2: TOST = 1024TOSC (drawing not to scale) This delay will not be there for INTRC and EXTRC osc mode.
3: GIE = ’1’ assumed. In this case after wake- up, the processor jumps to the interrupt routine. If GIE = ’0’, execution will
continue in-line.
4: CLKOUT is not available in XT, HS or LP osc modes, but shown here for timing reference.

Program Verification/Code Protection
If the code protection bit(s) have not been pro-
grammed, the on-chip program memory can be read
out for verification purposes.
9.10
ID Locations
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.
9.11
In-Circuit Serial Programming
PIC12C67X 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 volt-
age. This allows customers to manufacture boards with
unprogrammed devices, and then program the micro-
controller 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 the GP1 and GP0 pins low, while raising the
MCLR (VPP) pin from VIL to VIHH (see programming
specification). GP1 (clock) becomes the programming
clock and GP0 (data) becomes the programming data.
Both GP0 and GP1 are Schmitt Trigger inputs in this
mode.
Note:
Microchip does not recommend code pro-
tecting windowed devices.
After reset, and if the device is placed into program-
ming/verify mode, the program counter (PC) is at loca-
tion 00h. A 6-bit command is then supplied to the
device. Depending on the command, 14-bits of pro-
gram data are then supplied to or from the device,
depending if the command was a load or a read. For
complete details of serial programming, please refer to
the PIC12C67X Programming Specifications.
