Introduction
56F8346 Technical Data, Rev. 15
Freescale Semiconductor 43
Preliminary
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.
Note: Data Flash and Program RAM are NOT available on the 56F8146 device.
