CONTROL FUNCTIONS OF SUBSYSTEM CLOCK OSCILLATOR
The subsystem clock oscillator of the
PD750008 subseries has two control functions to decrease the supply
current.
The function to select with the software whether to use the built-in feedback resistorNote
The function to suppress the supply current by reducing the drive current of the built-in inverter when the supply
voltage is high (VDD
≥ 2.7 V)
Note When the subsystem clock is not used, set SOS.0 to 1 (not to use the built-in feedback resistor), connect
XT1 to VSS, and open XT2. This makes it possible to reduce the supply current required by the subsystem
clock oscillator.
Each function can be used by switching bits 0 and 1 in the sub-oscillator control register (SOS). (See Fig. 6-2.)
