12.10 In-Circuit Serial Programming™
ThePIC12F609/615/617/12HV609/615
microcontrollers can be serially programmed while in
the end application circuit. This is simply done with five
connections for:
• clock
• data
• 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 the GP0 and GP1 pins low, while raising the
MCLR (V
Programming Specification (DS41284) for more
information. GP0 becomes the programming data and
GP1 becomes the programming clock. Both GP0 and
GP1 are Schmitt Trigger inputs in Program/Verify
mode.
A typical In-Circuit Serial Programming connection is
shown in Figure 12-10.

12.11 In-Circuit Debugger
Since in-circuit debugging requires access to three pins,
MPLAB
not practical. A special 28-pin PIC12F609/615/617/
12HV609/615 ICD device is used with MPLAB ICD 2 to
provide separate clock, data and MCLR pins and frees
all normally available pins to the user.
A special debugging adapter allows the ICD device to
be used in place of a PIC12F609/615/617/12HV609/
615 device. The debugging adapter is the only source
of the ICD device.
When the ICD pin on the PIC12F609/615/617/
12HV609/615 ICD device is held low, the In-Circuit
Debugger functionality is enabled. This function allows
simple debugging functions when used with MPLAB
ICD 2. When the microcontroller has this feature
enabled, some of the resources are not available for
general use. Table 12-10 shows which features are
consumed by the background debugger.

Debugger User’s Guide” (DS51331), available on
Microchip’s web site (www.microchip.com).
