Abstract
PURPOSE: To increase an interruption processing speed and also to reduce firmware by allowing a processor unit to branch direct to a processing routine by a branch instruction from an interruption controller.
CONSTITUTION: Once a reception-transmission request signal is inputted to interruption controller CNT2, CNT2 sends an interruption request to processor unit PU1, which sends back an interruption permit signal to CNT2 if it is ready to receive the interruption. At the same time, CNT2 inserts a branch instruction into an interruption processing routine equivalent to data bus 4 by the interruption permit signal, and PU1 can branch from main routine M direct to processing routine Ma by the branch instruction from CNT2 and start reception data transfer process direct from address 00AA.
