Freescale Semiconductor
A separate self-clocked source (approximately1 kHz) for the real-time interrupt allows a wake up from
Stop2 or Stop3 Modes with no external components. When RTIS2:RTIS1:RTIS0 = 0:0:0, the real-time
interrupt function and this 1-kHz source are disabled. Power consumption is lower when the 1-kHz source
is disabled, but in that case the real-time interrupt cannot wake the MCU from stop.

MCU Memory
As shown in Figure 16, on-chip memory in the MC1321x series of MCUs consists of RAM, FLASH
program memory for non-volatile data storage, plus I/O and control/status registers. The registers are
divided into three groups:
Direct-page registers ($0000 through $007F)
High-page registers ($1800 through $182B)
Nonvolatile registers ($FFB0 through $FFBF)
