Questionable Frequency Event Query
Returns the decimal value of the sum of the bits in the Questionable Frequency
Event register.
NOTE
The register requires that the associated PTRansition or NTRansition filters be
set before a condition register bit can set a bit in the event register. The data in
this register is latched until it is queried. Once queried, the register is cleared.

Sequential command
Questionable Frequency Negative Transition
Determines which bits in the "Questionable Frequency Condition" on page 2804
register will set the corresponding bit in the "Questionable Frequency Event Query"
on page 2805 register when the condition register bit has a negative transition (1 to
0).
The variable <integer> is the sum of the decimal values of the bits that you want to
enable.
