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.

pic16f628а внутрисхемную отладку не поддерживает ?

Ругается: "Programming/Verify complete The target device is not ready for debugging. Please check your configuration bit settings and program the device before proceeding. The most common causes for this failure are oscillator and/or PGC/PGD settings."

Вполне возможно, что задействовали внешний кварц. И оно чуть конфликтует.

На фотке м/сх маркировка: PIC16F676-ICD

В простой PIC16F676 - не доклали отладчик ?
