4 MCU Memory Map (Internal Operation)
Figure 4–1 illustrates the MCU memory map under boot and normal operation. Note that the internal 256 bytes of
RAM are not shown since they are assumed to be in the standard 8052 location (0000 to 00FF). The shaded areas
represent the internal ROM/RAM.
When SDW–bit = 0 (boot–mode):
The 6K ROM is mapped to address (0x0000–0x17FF) and is duplicated in location
(0x8000–0x97FF) in code space. The internal 16K RAM is mapped to address range (0x0000–0x3FFF) in data
space. Buffers, MMR and I/O are mapped to address range (0xF800–0xFFFF) in data space.
When SDW–bit = 1 (normal mode):
The 6K ROM is mapped to (0x8000–0x97FF) in code space. The internal 16K
RAM is mapped to address range (0x0000–0x3FFF) in code space. Buffers, MMR and I/O are mapped to address
range (0xF800–0xFFFF) in data space.
