That is not the only difference. The ICD devices also have specific
debug hardware inside, which the standard parts don't have.
In larger devices the extra debugging hardware is always present, there
is no ICD versions, because the cost in money and chip area of the
debugging hardware is proportionally small, but for the smaller devices
this cost matters.
