Memory Maps

Introduction
The MC56F825x/MC56F824x device is based on the 56800E core. It uses a dual Harvard-style architecture with two
independent memory spaces for data and program. On-chip RAM is shared by both data and program spaces; flash memory is
used only in program space.
This section provides memory maps for:
Program address space, including the interrupt vector table
Data address space, including the EOnCE memory and peripheral memory maps
On-chip memory sizes for the device are summarized in Table 6. Flash memories’ restrictions are identified in the “Use
Restrictions” column of Table 6.

If CLKIN is selected as the device’s external clock input, both the GPS_C0 bit in GPS1 and the EXT_SEL bit in the OCCS
oscillator control register (OSCTL) must be set. In this case, it is also recommended to power down the crystal oscillator.
