Limitation point on the use of DFM
It’s prohibited to execute DFM enable/disable control in the SLOW mode (fs) (write to
DFMCR0<ACT1:0> = “10”). You should control DFM in the NORMAL mode.
If you stop DFM operation during using DFM (DFMCR0<ACT1:0> = “10”), you
shouldn't executions should be separated into two procedures as showing below.
If you stop high-frequency oscillator during using DFM (DFMCR0<ACT1:0> = “10”),
you should stop DFM before you stop high-frequency oscillator.
