■ EMBEDDED PROGRAM/DATA MEMORY (FLASH)
1.
Flash features
MB91F469Gx:
2112 Kbytes (32
× 64 Kbytes + 8 × 8 Kbytes = 16.5 Mbits)
Programmable wait state for read/write access
Flash and Boot security with security vector at 0x0024:8000 - 0x0024:800F
Boot security
Basic specification: Same as MBM29LV400TC (except size and part of sector configuration)
2.
Operation modes
(1) 64-bit CPU mode:
CPU reads and executes programs in word (32-bit) length units.
Flash writing is not possible.
Actual Flash Memory access is performed in d-word (64-bit) length units.
(2) 32-bit CPU mode :
CPU reads and executes programs in word (32-bit) length units.
Actual Flash Memory access is performed in word (32-bit) length units.
(3) 16-bit CPU mode :
CPU reads and writes in half-word (16-bit) length units.
Program execution from the Flash is not possible.
Actual Flash Memory access is performed in half-word (16-bit) length units.
Note: The operation mode of the flash memory can be selected using a Boot-ROM function. The function start
address is 0xBF60. The parameter description is given in the Hardware Manual in chapter 54.6 "Flash Access
Mode Switching".
