Internal Flash memory
Overview
The on-chip Flash is composed by one matrix module, 256 KBytes wide.
This module is on ST10 Internal bus, so it is called IFLASH
Figure 5.
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 internally generated.
The Data bus is 32-bit wide for fetch accesses to IFLASH, while it is 16 bit wide for read
accesses to IFLASH. Read/write accesses to IFLASH Control Registers area are 16 bit
wide.
