8KB Memory Window
The DiskOnChip 2000 memory map occupies a total address space of 8KB. This space consists of
four 2KB sections, as shown in Figure 5and described below.
Section 0
: Boot Block
This section includes data that is typically used for booting code from the CPU. The available
size is 64 bytes, aliased 32 times in the 2KB section. The second half of the boot block is
located in Section 2.
Section 1
: Boot Block
This section includes the second 64 bytes of the Boot Block. The first 64 bytes can be found in
Section 0, aliased 32 times.
Section 2
: Control Registers
Used to control the behavior of DiskOnChip 2000 and the flash media.
Section 3
: Flash Area Window
Used as a window to the flash media for data to be written or read.
