Real-Time Counter (S08RTCV1)
13.1 Introduction
The real-time counter (RTC) consists of one 8-bit counter, one 8-bit comparator, several binary-based and
decimal-based prescaler dividers, two clock sources, and one programmable periodic interrupt. This
module can be used for time-of-day, calendar or any task scheduling functions. It can also serve as a cyclic
wakeup from low power modes without the need for external components.
