Internal Flash memory
Overview
The on-chip Flash is composed of one matrix module of one bank of 512 Kbytes, named
Bank0, that can be read and modified. This module is called IFlash because it is on the
ST10 Internal bus.
Figure 6.
The programming operations of the Flash are managed by an embedded Flash
Program/Erase Controller (FPEC). The high voltages needed for Program/Erase operations
are generated internally.
The Data bus is 32-bit wide for fetch accesses to IFlash. Read/write accesses to IFlash
Control Registers area are 16-bit wide.

Module structure
The IFlash module is composed of a bank (Bank 0) of 512 Kbytes of program memory
divided in 12 sectors (B0F0...B0F11). Bank 0 also contains a reserved sector named Test-
Flash.
