4.6.1.2
Low Power Oscillator
The Low Power Oscillator (LPO) is comprised of two oscillators
— HF LPO and LF LPO, in a single
macro.
4.6.1.2.1 Features
The main features of the LPO are:
Supplies a clock at extremely low power for power-saving modes. This is connected as clock source #
4 of the Global Clock Module.
Supplies a high-frequency clock for non-timing-critical systems. This is connected as clock source # 5
of the Global Clock Module.
Provides a comparison clock for the crystal oscillator failure detection circuit.
Figure 4-5. LPO Block Diagram
Figure 4-5 shows a block diagram of the internal reference oscillator. This is a low power oscillator (LPO)
and provides two clock sources: one nominally 80KHz and one nominally 10MHz.
