20.2.5. Missing SmaRTClock Detector
The missing SmaRTClock detector is a one-shot circuit enabled by setting MCLKEN (RTC0CN.6) to 1.
When the SmaRTClock Missing Clock Detector is enabled, OSCFAIL (RTC0CN.5) is set by hardware if
SmaRTClock oscillator remains high or low for more than 100 µs.
A SmaRTClock Missing Clock detector timeout can trigger an interrupt, wake the device from a low power
mode, or reset the device. See Section “12. Interrupt Handler” on page 129, Section “14. Power Manage-
ment” on page 151, and Section “18. Reset Sources” on page 175 for more information.
Note: The SmaRTClock Missing Clock Detector should be disabled when making changes to the oscillator settings in
20.2.6. SmaRTClock Oscillator Crystal Valid Detector
The SmaRTClock oscillator crystal valid detector is an oscillation amplitude detector circuit used during
crystal startup to determine when oscillation has started and is nearly stable. The output of this detector
can be read from the CLKVLD bit (RTX0XCN.4).
Notes:
200
The CLKVLD bit has a blanking interval of 2 ms. During the first 2 ms after turning on the crystal
oscillator, the output of CLKVLD is not valid.
This SmaRTClock crystal valid detector (CLKVLD) is not intended for detecting an oscillator failure. The
missing SmaRTClock detector (CLKFAIL) should be used for this purpose.
