      Memory
      The HPC46064 has been designed to offer flexibility in
      memory usage. A total address space of 64 Kbytes can be
      addressed with 16 Kbytes of ROM and 512 bytes of RAM
      available on the chip itself. The ROM may contain program
      instructions, constants or data. The ROM and RAM share
      the same address space allowing instructions to be execut-
      ed out of RAM.
      Program memory addressing is accomplished by the 16-bit
      program counter on a byte basis. Memory can be addressed
      directly by instructions or indirectly through the B, X and SP
      registers. Memory can be addressed as words or bytes.
      Words are always addressed on even-byte boundaries. The
      HPC46064 uses memory-mapped organization to support
      registers, I/O and on-chip peripheral functions.
      The
      64 Kbytes and registers and I/O are mapped as shown in
      Table IV.
