2.3 Memory Map
The code memory space extends from 0000h to 1FFFh
(8 Kbytes) in a single 8-Kbyte panel. Addresses 0000h
through 01FFh, however, define a “Boot Block” region
that is treated separately from Panel 1. All code
memory is on-chip.
A user may store identification information (ID) in eight
ID registers. These ID registers are mapped in
addresses 200000h through 200007h. The ID locations
read out normally, even after code protection is applied.
Locations 300001h through 30000Dh are reserved
for the Configuration Words. These Words may be
set to select various device options and are
described in Section 5.0 “Configuration Word”.
These Configuration Words read out normally, even
after code protection.
Locations 3FFFFEh and 3FFFFFh are reserved for the
Device ID Words. These Words may be used by the
programmer to identify what device type is being
programmed and are described in Section 5.0
“Configuration Word”. These Configuration Words
read out normally, even after code protection.
