Arends Sent: Friday, August 22, 2008 9:27 AM To: 'Microcontroller discussion list - Public.' Subject: [PIC]ICSP of a 16F685 Programming a 16F628A i use RB6 and RB7 for PGC and PGD. But searching on the web and on the Microchip website i dont see anything about this on the 16F685 and looking on the datasheet i cant find PGM and PGD. Is there a document that handles the ICSP -> 16F685 or how should i connect the ICSP to this device.
