Table 5.4: Addresses and contents for the physical address space
Address range in absolute
addressing mode
0x00000 - 0x0FFFF
0x10000 - 0x1FFFF
0xC0000 - 0xFFFFF
When you want to read or modify software version-specific data, use logical
addressing. The following table contains a memory map for the 16-bit logical address
space.
Table 5.5: Addresses and contents for the logical address space
Address range in logical
addressing mode
0x0000 - 0xAFFF
0xB000 - 0xCFFF
0xD000 - 0xFFFF
If you give the ADDR command with no parameter, it displays the current
addressing mode. All parameters must be entered in lower case.
EXAMPLE
dbg>addr a
sm and rm commands apply absolute addressing.
dbg>addr l
sm and rm commands apply logical addressing.
dbg>addr
sm and rm commands apply logical addressing.

Overlaps the corresponding
area in physical address
space.
Banked code overlaps the
following areas in the
physical address space:
0xB000 – 0xCFFF
