Special Function Registers (SFRs)
An SFR (special function register) is a control register for a peripheral function.
Table 4.1 to Table 4.13 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.
