Abstract
PURPOSE: To increase the points of a timer in one module sharply, by means of constituting a plurality of timers by using one time counter.
CONSTITUTION: A timer module 10 generates a CPU stop requiring signal every time count period, and when the CPU may receive this, a status signal indicating that it becomes to a timer mode, is sent. When a CPU block 20 receives this signal, it causes the operation of the CPU block to be whether stopped or the CPU block to be floated from a data bus 40. The timer module 10 has a memory which has a plurality of memorized positions those memorize a set value and a present value of the timer, and has a memory circuit which memorizes flags, and it counts down the present value of the memory circuit in which flags are set, every time count period by one, and when this value becomes to 0, a time up signal is generated.
