7.1.1
• LTBC generates T32KHZ to T1HZ signals by dividing the low-speed clock (LSCLK) frequency.
• LTBC allows frequency adjustment (Adjustment range: Approx. −488ppm to +488ppm. Adjustment accuracy:
• HTBC generates HTB1 to HTB32 signals by dividing the high-speed clock (HSCLK) frequency.
• Capable of generating 128Hz , 64Hz , 32Hz , 16Hz , 8Hz , 4Hz , 2Hz, and 1Hz interrupts.
7.1.2
This LSI includes a low-speed time base counter (LTBC) and a high-speed time base counter (HTBC) that generate
base clocks for peripheral circuits. By using the time base counter, it is possible to generate events periodically.
For input clocks, see Chapter 6, “Clock Generation Circuit”. For interrupt permission, interrupt request flags, etc.,
described in this chapter, see Chapter 5, “Interrupts”.
Figure 7-1 and Figure 7-2 show the configuration of a low-speed time base counter and a high-speed time base counter,
respectively.
Approx. 0.48ppm) by using the low-speed time base counter frequency adjustment registers (LTBADJH and
LTBADJL).
