Preliminary
Part 4 Memory Map
4.1 Introduction
The 56F8347 device is a 16-bit motor-control chip based on the 56800E core. It uses 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 each device are summarized in Table 4-1. Flash memories’ restrictions
are identified in the “Use Restrictions” column of Table 4-1.
4.2 Program Map
The operating mode control bits (MA and MB) in the Operating Mode Register (OMR) control the
Program memory map. At reset, these bits are set as indicated in Table 4-2. Table 4-4 shows the
memory map configurations that are possible at reset. After reset, the OMR MA bit can be changed
and will have an effect on the P-space memory map, as shown in Table 4-3. Changing the OMR
MB bit will have no effect.

Table 4-2 OMR MB/MA Value at Reset
OMR MB =
Flash Secured
State1, 2
1.
This bit is only configured at reset. If the Flash secured state changes, this will not be reflected in MB until the next reset.
2.
Changing MB in software will not affect Flash memory security.
OMR MA =
EXTBOOT Pin
Chip Operating Mode
0
Mode 0 – Internal Boot; EMI are configured to use 16 address lines; Flash
Memory is secured; external P-space is not allowed; the EOnCE is disabled
0
1
Not valid; cannot boot externally if the Flash is secured and will actually
configure to 00 state
1
0
Mode 0 – Internal Boot; EMI is configured to use 16 address lines
1
Mode 1 – External Boot; Flash Memory is not secured; EMI configuration is
determined by the state of the EMI_MODE pin
