Limitation point on the use of DFM
1.
2.
3.
Examples of setting are below.
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 execute the commands that change the clock f
DFM at the same time. Therefore the above execution 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.
