can program the EEPROM and flash ROM memory cells of supported AVR
parts. Where supported by the serial instruction set, fuse bits and
lock bits can be programmed as well. These are implemented within

as seperate memory types and can be programmed using data from a file
(see the
.Fl m
option) or from terminal mode (see the

and

commands). It is also possible to read the chip (provided it has not

interactively communicate with the MCU, and to display or program
individual memory cells.
