Slow Clock RC Oscillator
Slow Clock Selection
AT91SAM9M10
Figure 25-2. Typical Slow Clock Crystal Oscillator Connection
The user has to take into account the possible drifts of the RC Oscillator. More details are given
in the section “DC Characteristics” of the product datasheet.
The AT91SAM9M10 slow clock can be generated either by an external 32,768 Hz crystal or by
the on-chip RC oscillator. The 32,768 Hz crystal oscillator can be bypassed by setting the bit
OSC32BYP to accept an external slow clock on XIN32.
The internal RC oscillator and the 32,768 Hz oscillator can be enabled by setting to 1, respec-
tively, RCEN bit and OSC32EN bit in the System Controller user interface. The OSCSEL
command selects the slow clock source.
Figure 25-3. Slow Clock Selection
RCEN, OSC32EN,OSCSEL and OSC32BYP bits are located in the Slow Clock Control Register
(SCKCR) located at address 0xFFFFFD50 in the backed up part of the System Controller and so
are preserved while VDDBU is present.
After a VDDBU power on reset, the default configuration is RCEN=1, OSC32EN=0 and OSC-
SEL=0, allowing the system to start on the internal RC oscillator.
The programmer controls the slow clock switching by software and so must take precautions
during the switching phase.
