Abstract
A microcomputer comprising a CPU for outputting a signal requesting generation of pulses when receiving an erase signal requesting processing to initialize a flash memory unit; a timer for generating the pulses when receiving the signal requesting generation of the pulses output by the CPU wherein the frequency of a system clock is divided to produce clock pulses and each of the pulses is generated whenever the number of clock pulses reaches a set value; and a memory control unit for executing the processing to initialize the flash memory unit as well as measuring a time it takes to carry out the processing by counting the number of pulses output by the timer when receiving the erase signal.
