Caution
Use the basic timer after setting bit 0 (DTSCK0) of the DTS system clock select register (DETSCK)
to 1 after power application, and after reset by the RESET pin (refer to 5.1 Functions of Clock
Generator).
The first interrupt request signal (INTBTM0) after the DTSCK0 flag has been set is generated
within 100 to 140 ms. The second signal and those that follow are generated at intervals of 100
ms.
