This is the only option that is mandatory for every invocation of
.Nm avrdude .

This option specifies the MCU connected to the programmer. The MCU

Both can be used with the -p option. If -p ? is specified with a specific
programmer, see -c below, then only those parts are output that the
programmer expects to be able to handle, together with the programming
interface(s) that can be used in that combination. In reality there can be
deviations from this list, particularly if programming is directly via a
bootloader.
