Internal Data Memory: The Internal data memory provides 256 bytes (0x00 to 0xFF) of data memory. The internal data
memory address is always 1 byte wide and can be accessed by either direct or indirect addressing. The Special Function
Registers occupy the upper 128 bytes. This SFR area is available only by direct addressing. Indirect addressing
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) select which bank is in use. The next 16 bytes form a
block of bit-addressable memory space at bit addressees 0x00-0x7F. All of the bytes in the lower 128 bytes are accessible
through direct or indirect addressing. Table 5 shows the internal data memory map.
Special Function Registers (SFRs)
A map of the Special Function Registers is shown in Table 6.
Only a few addresses are occupied, the others are not implemented. SFRs specific to the 651X are shown in bold print. Any
read access to unimplemented addresses will return undefined data, while any write access will have no effect. The registers
at 0x80, 0x88, 0x90, etc., are bit-addressable, all others are byte-addressable.
