摘要： A microcomputer capable of reducing a board area, enhancing the security, and improving the usability is provided. A microcomputer to be used in a notebook PC is disclosed, in which programs of a keyboard/power management BIOS and a system BIOS are stored in a built-in flash memory ROM. In order to set read (R)/write (W) protect to the BIOSes stored in the flash memory ROM, a read/write protect setting register is provided, and at initial setting after the release of reset, flags of R/W permission, R permission/W prohibition, W permission/R prohibition, and R/W prohibition are set to this register by a central processing unit CPU. By doing so, it becomes possible to achieve protection such as the prevention of error writing of the BIOS and the like between a host machine and the flash memory ROM via a LPC bus.

摘要： The present invention provides a one-chip microcomputer that can realize the control of cooling equipment, the control of the brightness of a display device, and the control of the charge and discharge of a battery without mounting an analog circuit. The one-chip microcomputer is used in a notebook-size personal computer, and comprises: a CPU that performs operation processing; a CPG that generates a clock signal; a flash memory that stores a control program; a RAM that sores data; an 8-bit timer that controls fans; and a 14-bit timer that controls an LCD brightness controller of an LCD and a voltage charger of batteries. The one-chip microcomputer controls the fans by the 8-bit timer without mounting the analog circuit and can adjust the LCD brightness by the 14-bit timer.

摘要： A flash memory is provided with a protect area PA in which reading of a specific block is prohibited. A RAM to be used as a work area of a program is provided with a protect area PA1 in which reading of a specific block is prohibited. A bus state controller 3 compares a value of a program counter and a value of an address signal to prohibit reading in areas other than the protect area PA in the flash memory and to prohibit reading of data of protect area PA1 in the RAM other than reading from the protect area PA of the flash memory. For instance, when a user reads data of the protect area PA from a user access area to which the user can access, senseless data such as H'FFFF are output from the bus state controller 3 via a data bus.
