Questionable Frequency Condition
Returns the decimal value of the sum of the bits in the Questionable Frequency
Condition register.
NOTE
The data in this register is continuously updated and reflects the current
conditions.
Remote Command

Questionable Frequency Enable
Determines which bits in the "Questionable Frequency Condition" on page 2602
Register will set bits in the "Questionable Temperature Event Query" on page 2600
register, which also sets the Frequency Summary bit (bit 5) in the "Questionable
Register" on page 2592.
The variable <integer> is the sum of the decimal values of the bits you want to
enable.
