<p>PURPOSE:To replace an incorporated circuit group by the outside and to debug an applied system from the initial stage of design concerning the microcomputer which incorporates the circuit group to be defined by a user. CONSTITUTION:An operation mode terminal 106 is added to a microcomputer 100 and at the level of the mode terminal 106, signals required to the interface by a central processing unit(CPU) 101 and an SOG area 102 are guided to terminals 107, 108 and 109 in place of a signal line from the SOG area 102.</p> |
