Part 4 Memory Map
4.1 Introduction
The 56F8322 and 56F8122 devices are 16-bit motor-control chips based on the 56800E core. These parts
use a Harvard-style architecture with two independent memory spaces for Data and Program. On-chip
RAM and Flash memories are used in both spaces.
This section provides memory maps for:
On-chip memory sizes for the device are summarized in
identified in the “Use Restrictions” column of
Note: Data Flash and Program RAM are NOT available on the 56F8122 device.
4.2 Program Map
The Program Memory map is located in
Operating Mode Register (OMR) usually control the Program Memory map. Because the 56F8322 and
56F8122 do not include EMI, the OMR MA bit, which is used to decide internal or external BOOT, will
have no effect on the Program Memory Map. OMR MB reflects the security status of the Program Flash.
After reset, changing the OMR MB bit will have no effect on the Program Flash.
