This LSI includes a 1 kHz timer to measure 1/1000 seconds.
The 1 kHz timer counts the 1 kHz(*) signal created by dividing the T2KHZ output frequency (*) of the low-speed time
base counter (LTBC) and generates a 10 Hz or 1 Hz interrupt (1 kHz timer interrupt).
With the 1 kHz timer, 1/1000 second, which is difficult to generate on a time-base-counter basis, represented by a
decimal number can be obtained easily. The timer can be applied to period measurement for stopwatches.
For the timer base counter, see Chapter 7, “Time Base Counter”.
Figure 9-1 shows the configuration of the 1 kHz timer.
