PURPOSE:To enable generation of timing pulse after set time regardless of absolute time by reflecting the counting value of a counter in the point of time when a trigger for timer driving is applied, to the set time. CONSTITUTION:A clock pulse generated by a clock pulse generator 1 is counted at all times by a counter 2. The counter 2 disregards overflow. When a trigger 4 is applied to the first channel, the contents of a register 5 and the contents of the counter 2 at the point of time are sent to an adder 3, and the result is written in the register 5 again. At the same time, the counting value of the counter 2 and the contents of the reset register 5 are compared by a comparator 6, and when they coincide, a signal is sent to a timing pulse generator 7 to output a timing pulse. |
