PURPOSE:To reduce a load due to reset at the time of restarting and to attain high speed operation by providing a local processor with a means for informing the sort of reset. CONSTITUTION:When a power supply is turned on, a reset signal is inputted to the local processor 6 by a reset control mechanism 2 and the processor 6 is restarted to read out the value of a reset state holding means 11. Since the values of MRST and H/WRST are set up to '1', the write/read check of an optical value is executed and then a value saved in a register is written. Thus, the preceding value can be held in the case of reset other than the connection of the power supply. |
