Considering the use of the 16LF877 micro combined with 3.3 volt logic in a product. We need in circuit programability and we curently use a PRO MATE with the ICSP module. Is this going to work for 3.3 volt parts? It looks as though Vdd can be adjusted from within the programming dialogue in MPLAB. Has anyone tried this?
