PIC16F627A/628A/648A
14.13 In-Circuit Debugger
Since in-circuit debugging requires the loss of clock,
®
data and MCLR pins, MPLAB
ICD 2 development with
an 18-pin device is not practical. A special 28-pin
PIC16F648A-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. Debugging of all
three versions of the PIC16F627A/628A/648A is
supported by the PIC16F648A-ICD.
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 an 18-pin
socket that plugs into the user’s target via an 18-pin
stand-off connector.
When the ICD pin on the PIC16F648A-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 14-19
shows which features are consumed by the background
debugger.
