<p>PURPOSE:To shorten a reset sequence period and to process the data at high speed by processing a setting based on a writing control signal generated in terms of hardware by means of a reference clock, etc., without processing the setting based on the writing control signal generated in terms of software by means of a control means, etc., at the time of processing the settinng of an operation mode. CONSTITUTION:This information processor is provided with an input/output means 11 controlling the input/output of the external control signal SR or operation mode data Dm, a storage means 12 storing the operation mode data DM or another data D and the control means 13 controlling the input/output of the input/output means 11 and the storage means 12. The processor is constituted by providing a mode register MR in the input/output means 11 and fetching the value of a data bus 15 only based on a first reed operation after reset release by the mode register MR.</p> |
