10. Hold mode
When the clock function is enabled, if the HOLD pin goes from high to low input to the FMIN, AMIN and HCTR
pins will be disabled, and the system will go to a state where only the clock operates. This is called hold mode.
When the HOLD pin goes from low to high, hold mode is cleared and the system returns to normal mode.
11. Backup mode
When the clock function is disabled, if the HOLD pin goes from high to low input to the FMIN, AMIN and HCTR
pins will be disabled, the 4.5 MHz crystal oscillator will be stopped and the system will go to a power saving mode.
This is called backup mode.
When the HOLD pin goes from low to high, hold mode is cleared and the system returns to normal mode 75 ms*
later.
Note: All output ports go to the high-impedance state during this period.
