<p>PURPOSE:To obtain a microprocessor having a wide range of application by discriminating a reset state caused by a power-on action or a manual action via a CPU itself. CONSTITUTION:A CPU 11 decides a reset state caused by a power-on action in case a resetting circuit 15 works in a 1st status S1. Then the CPU 11 decides a manual reset state set by a resetting switch 17 when the circuit 15 works in a 2nd status S2 with some delay secured from the power-on state. Then an initialization is carried out when a power-on reset state is confirmed. While the initialization program is not carried out and the step 1 set immediately after the initialization program is carried out in case a manual reset state is confirmed.</p> |
