When 0 is w ritten to the CSPROINI bit in the OFS register, the value after reset is 10000000b.
Write 0 before w riting 1 to set the CSPRO bit to 1. 0 cannot be set by a program.
The OFS register is on the flash memory. Write to the OFS register w ith a program. After w riting is completed, do not
w rite additions to the OFS register.
To use the pow er-on reset, set the LVD0ON bit to 0 (voltage monitor 0 reset enabled after hardw are reset).
