Memory Organization
Figure 6 shows the memory organization of the
VMX51C1020.
At power-up/reset, the code is executed from the
56Kx8 Flash memory mapped into the processor’s
internal Program space.
A 1KB block of RAM is also mapped into the
external data memory of the VMX51C1020. This
block can be used as general-purpose scratch pad
or storage memory. A 256 byte block of RAM is
mapped to the internal data memory space. This
block of RAM is broken into 2 sub-blocks, with the
upper block accessible via indirect addressing and
the lower block accessible via both direct and
indirect addressing.
The following figure describes the access to the
lower block of 128 bytes.

The SFR (Special Function Register) space is also
mapped into the upper 128 bytes of internal data
memory space. This SFR space is only accessible
using direct-access. The SFR space provides the
interface to all the on-chip peripherals. This
interfacing is illustrated in Figure 8.
