The blank regions are reserved. Do not access locations in these regions.
Software reset, watchdog timer reset, voltage monitor 1 reset, or voltage monitor 2 reset do not affect this register.
The LVD0ON bit in the OFS register is set to 1 and hardware reset.
Power-on reset, voltage monitor 0 reset, or the LVD0ON bit in the OFS register is set to 0 and hardware reset.
Software reset, watchdog timer reset, voltage monitor 1 reset, or voltage monitor 2 reset do not affect b2 and b3.
The CSPROINI bit in the OFS register is set to 0.
