Internal Data Memory Map and Access
The Internal data memory provides 256 bytes (0x00 to 0xFF) of data memory. The internal data memory
address is always 1 byte wide. Table 10 shows the internal data memory map.
The Special Function Registers (SFR) occupy the upper 128 bytes. The SFR area of internal data memory
is available only by direct addressing . Indirect addressing of this area accesses the upper 128 bytes of
Internal RAM. The lower 128 bytes contain working registers and bit addressable memory. The lower 32
bytes form four banks of eight registers (R0-R7). Two bits on the program memory status word ( PSW, SFR
0xD0 ) select which bank is in use. The next 16 bytes form a block of bit addressable memory space
at addresses 0x00-0x7F. All of the bytes in the lower 128 bytes are accessible through direct or indirect
addressing.

Special Function Registers (SFRs)
A map of the Special Function Registers is shown in Table 11 .
Only a few addresses in the SFR memory space are occupied, the others are not implemented. A read
access to unimplemented addresses returns undefined data, while a write access has no effect. SFRs
specific to the 71M6545/H are shown in bold print on a gray field. The registers at 0x80, 0x88, 0x90,
etc., are bit addressable, all others are byte addressable.
