LVIMD flag
LVIRF flag
LVIF flag
The LVIMK flag is set to “1” by reset signal generation.
LVIRF is bit 0 of the reset control flag register (RESF).
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 RESF, see CHAPTER 18 RESET FUNCTION.
