15.11 In-Circuit Debugger
In-circuit debugging requires clock, data and MCLR
pins. A special 28-pin PIC16F785 ICD device is used
with MPLAB
ICD 2 to provide separate clock, data
and MCLR pins so that no pins are lost for these func-
tions leaving all 18 of the PIC16F785 I/O pins available
to the user during debug operation.
This special ICD device is mounted on the top of a
header and its signals are routed to the MPLAB ICD 2
connector. On the bottom of the header is a 20-pin
socket that plugs into the user’s target via the 20-pin
stand-off connector.
When the ICD pin on the PIC16F785 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 15-9 shows which fea-
tures are consumed by the background debugger:
