Function
The TMP93CS20 includes a timer which is used for a clock operation.
An interrupt (INTRTC) can be generated each 0.25 s or 0.50 s by using a low-frequency clock
A timer for real time clock can operate in all mode in which a low-frequency oscillation is
In addition, INTRTC can return from each standby mode except STOP mode.
The timer for real time clock is controlled by a timer for real time clock control register
Figure 3.13.2 shows the timer for real time clock control register.
