12.10 In-Circuit Serial Programming™
The PIC16F610/616/16HV610/616 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 RA0 and RA1 pins low, while raising the
MCLR (V
Programming Specification (DS41284) for more
information. RA0 becomes the programming data and
RA1 becomes the programming clock. Both RA0 and
RA1 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 PIC16F610/616/
16HV610/616 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 PIC16F610/616/16HV610/616
device. The debugging adapter is the only source of the
ICD device.
When the ICD pin on the PIC16F610/616/16HV610/
616 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 12-9 shows which features are consumed
by the background debugger.
