Limitation point on the use of DFM
1. It’s prohibited to execute DFM enable/disable control in the SLOW mode (fs)
2. If you stop DFM operation during using DFM (DFMCR0<ACT1:0> = “10”), you shouldn’t
3. If you stop high-frequency oscillator during using DFM (DFMCR0<ACT1:0> = “10”), you
(write to DFMCR0<ACT1:0> = “10”). You should control DFM in the NORMAL mode.
execute the commands that change the clock f
time. Therefore the above executions should be separated into two procedures as showing
below.
should stop DFM before you stop high-frequency oscillator.
(1) Start up/change control
(OK) Low-frequency oscillator operation mode (fs) (High-frequency oscillator STOP) →
High-frequency oscillator start up → High-frequency oscillator operation mode (f
DFM start up → DFM use mode (f
(OK) Low-frequency oscillator operation mode (fs) (High-frequency oscillator operate) →
High-frequency oscillator operation mode (f
(f
(Error) Low-frequency oscillator operation mode (fs) (High-frequency oscillator STOP)
→ High-frequency oscillator start up → DFM start up → DFM use mode (f
