12.11 In-Circuit Debugger
Since in-circuit debugging requires the loss of clock,
data and MCLR pins, MPLAB
an 8-pin device is not practical. A special 14-pin
PIC12F683 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 PIC12F683 device. The
debugging adapter is the only source of the ICD device.

Preliminary
When the ICD pin on the PIC12F683 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:

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