1. SFR registers with least significant nibble address equal to 0 or 8 are bit-addressable.
2. NVERS reset value depends on the silicon version: 1000 0100 for AT89C51SND1C product and 0000 0001 for AT83SND1C
3. FCON register is only available in AT89C51SND1C product.
4. FCON reset value is 00h in case of reset with hardware condition.
5. CKCON reset value depends on the X2B bit (programmed or unprogrammed) in the Hardware Byte.
