0 FCLKDIV register has not been written
1 FCLKDIV register has been written since the last reset
Clock Divider Bits — FDIV[6:0] must be set to effectively divide OSCCLK down to generate an internal Flash
clock, FCLK, with a target frequency of 1 MHz for use by the Flash module to control timed events during program
and erase algorithms.
