The MC1323x real-time counter module consists of one 16-bit counter, one 16-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 (STOP2, STOP3 and WAIT). RTC can be clocked from
bus clock, the optional 32.768 kHz oscillator or the onboard 1 kHz low power oscillator.
Features of the RTC module include:

Development support for the HCS08 on the MC1323x includes the background debug controller (BDC)
and the on-chip debug module (DBG). The BDC provides a single-wire (signal BKGD) debug interface
to the MCU that provides a convenient interface for programming the on-chip FLASH and other storage.
The BDC is also the primary debug interface for development and allows non-intrusive access to memory
data and traditional debug features such as CPU register modify, breakpoints, and single instruction trace
commands.
Address and data bus signals are not available on external pins. Debug is done through commands fed into
the MCU via the single-wire background debug interface. The debug module provides a means to
selectively trigger and capture bus information so an external development system can reconstruct what
happened inside the MCU on a cycle-by-cycle basis without having external access to the address and data
signals. Features include:
