15 / 57 page R8C/35C Group 4. Special Function Registers (SFRs) R01DS0006EJ0100 Rev 1.00 Page 15 of 54 Aug. 24, 2010 4. Special Function Registers (SFRs) An SFR (special function register) is a control register for a peripheral function. Tables 4.1 to 4.12 list the special function registers and Table 4.13 lists the ID Code Areas and Option Function Select Area. Table 4.1 SFR Information (1) (1) X: Undefined Notes: 1. The blank areas are reserved and cannot be accessed by users. 2. The CWR bit in the RSTFR register is set to 0 after power-on and voltage monitor 0 reset. Hardware reset, software reset, or watchdog timer reset does not affect this bit. 3. The CSPROINI bit in the OFS register is set to 0. 4. The LVDAS bit in the OFS register is set to 1. 5. The LVDAS bit in the OFS register is set to 0.
