Abstract: PROBLEM TO BE SOLVED: To add an exclusive bit to an operation code decoding column and to force data access generated in the page '0' of a random access memory(RAM) for an instruction. SOLUTION: A user can select an arbitrary page and can directly access to a specified function register positioned in the page '0' of RAM 22 or to a register variable. Setting of an exclusive bit does not affect present operation of a micro controller 20, or setting of the bit does not correct and address which is stored in an operation code instruction executed at present by the micro controller and is selected at present.

Abstract: PROBLEM TO BE SOLVED: To enable plural circuit boards to flexibly perform multiple connection to a serial bus. SOLUTION: An original software address must be allocated to each circuit board 12 before the board 12 can be used together with other circuit boards on a common serial bus 18. The original software address is allocated when a bus master device 20 outputs an address allocation command and the command utilizes an original serial number that is stored in each board 12. This address allocation command inquires each board 12 which is connected to the bus 18 and allocates an original software address to each board 12 which responds completely. An address allocation command is repeatedly issued to each board 12 on the bus 18 until the original software address is allocated to all of the boards 12 on the bus 18.

Abstract: A pulse width modulated (PWM) trapezoidal commutation drive to a brushless direct current (BLDC) motor is sine modified so that the applied drive voltage substantially matches the induced voltage generated in the BLDC motor. The values of the cosine of the angles between -30 degrees and +30 degrees are used to modify the duty cycle of the PWM drive signal dependent upon the rotor angular positions determined from the times between the zero crossing BEMF voltages measured at the unconnected motor terminals.

Abstract: An analog-to-digital (ADC) controller is used in combination with a digital processor of a microcontroller to control the operation of capacitance measurements using the capacitive voltage division (CVD) method. The ADC controller handles the CVD measurement process instead of the digital processor having to run additional program steps for controlling charging and discharging of a capacitive touch sensor and sample and hold capacitor, then coupling these two capacitors together, and measuring the resulting voltage charge thereon in determining the capacitance thereof. The ADC controller may be programmable and its programmable parameters stored in registers.
