LVIMD flag
LVION flag
LVIRF flag
The LVIMK flag is set to “1” by reset signal generation.
LVIRF flag is bit 0 of the reset control flag register (RESF).
POR
PDR
When the LVI default start function (bit 0 (LVIOFF) of 000C1H = 0) is used, the LVIRF flag may become 1
from the beginning due to the power-on waveform.
For details of the RESF register, see CHAPTER 21 RESET FUNCTION.
