The PIC Programmer (2)

• PIC programing takes place serially, one bit at a time

• The programming protocol makes use of a series of commands to be issued to the PIC; the comand form is 24-bit long, (8 bits of code, 16 bits of data)

• The PIC pins used are RB6 (clock input), RB7 (I/O data), MCLR (program mode)
