Enable bits for the individual FROs. A '1' in bit [n] enables FRO 'n'.
Default state is all '1's to enable all FROs after power-up. Note that
they are not actually started up before the CTL.TRNG_EN bit is set
to '1'. Bits are automatically forced to '0' here (and cannot be written
to '1') while the corresponding bit in ALARMSTOP.FRO_FLAGS has
value '1'.
