发明名称 Incoming notification pattern setting circuit and method of portable telephone
摘要 It is constructed so that combinations of display colors or lighting patterns can be set from the outside by incoming notification means by light of a portable telephone apparatus. That is, incoming notification pattern data by a change in lighting colors and data of the tempo are stored in RAM 3, and data from the RAM 3 is held in an FIFO 8 and is outputted every tempo according to a read signal from an FIFO read signal generator 9, and also by generating an interruption at the time when a predetermined amount of data is outputted, a CPU 1 writes subsequent data from the RAM 3 to the FIFO 8 according to the interruption. Then, data read from the FIFO 8 is once held in an output port register 5 and an LED driver 6 independently drives plural LEDs according to data outputted from the output port register 5. In this case, it is constructed so that the data from the RAM 3 can be set from the outside.
