Chapter 13 Real-Time Counter (S08RTCV1)
13.1.3
The block diagram for the RTC module is shown in
13.2
The RTC does not include any off-chip signals.
13.3
The RTC includes a status and control register, an 8-bit counter register, and an 8-bit modulo register.
Refer to the direct-page register summary in the memory section of this document for the absolute address
assignments for all RTC registers.This section refers to registers and control bits only by their names and
relative address offsets.
