If a 32.678-kHz oscillator is used, then perform the following steps:<br />1. Write 0x44 to the HIBCTL register at offset 0x10 to enable the oscillator input.<br />2. No delay is necessary.<br />The above is only necessary when the entire system is initialized for the first time. If the processor<br />is powered due to a wake from hibernation, then the Hibernation module has already been powered<br />up and the above steps are not necessary. The software can detect that the Hibernation module<br />and clock are already powered by examining the CLK32EN bit of the HIBCTL register.
