The C511/513 CPU manipulates operands in the following four address spaces:
– up to 64 Kbyte of external program memory
– up to 16 Kbyte of internal program memory
– up to 64 Kbyte of external data memory
– up to 256 bytes of internal data memory (includes bitaddressable area of 128 bits)
– 256 bytes additional internal data memory (XRAM)
– a 128 byte special function register area with 16 bitaddressable registers (128 bits)
Figure 3-10 illustrates the memory address spaces of the C511/513.
