Preliminary Technical Data
MEMORY MAPPED REGISTERS
The Memory Mapped Register (MMR) space is mapped into
the top 4kBytes of the MCU memory space and accessed by
indirect addressing, load and store commands, through the
ARM7 banked registers. An outline of the ADuC7032s Memory
Mapped Register Bank is shown in Figure 14.
The MMR space provides an interface between the CPU and all
on-chip peripherals. All registers except the ARM7 core
registers (described in ARM Registers) reside in the MMR area.
As can be seen from the detailed MMR map in Table 17, the
MMR data widths vary from 1 Byte (8 bits) to 4 Bytes (32 bits).
The ARM7 core can access any of the MMRs (single byte or
multiple byte width registers) with a 32 bit read or write access.
The resultant read for example, aligned per ‘little endian’
format described earlier. However, errors will result if the
ARM7 core tries to access 4 Byte (32 bit) MMRs with a 16-bit
access. In the case of a (16-bit) write access to a 32-bit MMR,
the (upper) 16 most significant bits will be written as 0’s. More
obviously, in the case of a 16-bit read access to a 32-bit MMR,
only 16 of the MMR bits can be read.
