6.3 Subsystem Clock Oscillator Control Functions
The
μ
PD753017A subsystem clock oscillator has the following two control functions.
Selects by software whether an internal feedback resistor is to be used or not
Note
.
Reduces current consumption by decreasing the drive current of the on-chip inverter when the supply voltage
is high (V
DD
2.7 V).
Note
When the subsystem clock is not used, set SOS.0 to 1 (so as not to use the internal feedback resistor)
by software, connect XT1 to V
SS
, and open XT2. This makes it possible to reduce the current
consumption in the subsystem clock oscillator.
The above functions can be used by switching the bits 0 and 1 of the sub-oscillator control register (SOS).
