The MFP programmer (called PEEPROM, too) is an EEPROM programmer
developed and intended for the EM66xx microcontroller family. It has to be
connected to a PC and communicates with a telegram-oriented protocol. The MFP
immediately interprets each telegram coming from the PC. By means of this
protocol, the PC can send orders and control the system (download data's, program
device, calculate CRC). First the data have to be downloaded from the PC to the
buffer of the programmer. In order to detect if a transmission error occurred, the PC
asks the programmer to calculate the CRC (cyclic redundancy checksum) and
checks if it fits with its own CRC. After that, the PC can either control the
programming cycles or switch the programmer in a stand-alone mode. In this state,
the MFP can be disconnected and programming is controlled by means of the
programming button. The status LED's indicate what the MFP is doing and if
programming cycle has been successfully terminated.
