12.11 In-Circuit Debugger
Since in-circuit debugging requires the loss of clock,
data and MCLR pins, MPLAB
with 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.
This special ICD device is mounted on the top of the
header and its signals are routed to the MPLAB ICD 2
connector. On the bottom of the header is an 8-pin
socket that plugs into the user’s target via the 8-pin
stand-off connector.
When the ICD pin on the PIC12F683-ICD device is
held low, the In-Circuit Debugger functionality is
enabled. This function allows simple debugging
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:
