Preliminary
3.5 Registers
When referring to the register definitions for the OCCS in the 56F8300 Peripheral User Manual, use the
register definitions with the internal Relaxation Oscillator, since the 56F8323 and 56F8123 contain this
oscillator.
Part 4 Memory Map
4.1 Introduction
The 56F8323 and 56F8123 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:
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 4-1. Flash memories’ restrictions are
identified in the “Use Restrictions” column of Table 4-1.
Note: Data Flash and Program RAM are NOT available on the 56F8123 device.
4.2 Program Map
The Program Memory map is located in Table 4-2. The operating mode control bits (MA and MB) in the
Operating Mode Register (OMR) control the Program Memory map. Because the 56F8323 and 56F8123
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.
