Special Function Registers (SFRs) An SFR (special function register) is a control register for a peripheral function. Table 4.1 to Table 4.6 list the SFR Information. Table 4.1 SFR Information (1)(1) X: Undefined NOTES: 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. 8. The CSPROINI bit in the OFS register is 0.
