Real-Time Counter (S08RTCV1)
15.1
Introduction
The RTC module consists of one 8-bit counter, one 8-bit comparator, several binary-based and
decimal-based prescaler dividers, three 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
wake up from low power modes without the need of external components.
All devices in the MC9S08DZ60 Series feature the RTC.
