VCXOID
Voltage Controlled External Oscillator Lock Detection
The VCXOID is used to indicate whether the internal clock refer-
ence is locked to an external VCO. An interrupt will not occur
unless the VCXOIE is set to "1" in the channel register 0x00h.
"0" = No Alarm
"1" = No lock has occured for VCXO
