Special Function Registers (SFRs)
1. The blank regions are reserved. Do not access locations in these regions.
2. Software reset, watchdog timer reset, and voltage monitor 2 reset do not affect this register.
3. The LVD0ON bit in the OFS register is set to 1.
4. Power-on reset, voltage monitor 1 reset or the LVD0ON bit in the OFS register is set to 0.
5. Software reset, watchdog timer reset, and voltage monitor 2 reset do not affect b2 and b3.
6. Software reset, watchdog timer reset, and voltage monitor 2 reset do not affect b7.
7. Software reset, the watchdog timer rest, and the voltage monitor 2 reset do not affect other than the b0 and b6.
