Questionable Status Register

Questionable Status Register
This register consists of CONDITION, TRANSITION FILTER, EVENT, and event
enable (MASK) registers.
• You enable the desired bits of the EVENT register by using the MASK register.
1 enables, 0 masks the corresponding bit of EVENT register. The MASK
register is set by the :STATus:QUEStionable:ENABle command.
• The TRANSITION FILTER register consists of positive and negative transition
filters.
If a bit in the positive transition filter is set to 1, then a 0 to 1 transition in the
corresponding bit of the CONDITION register causes a 1 to be written in the
corresponding EVENT register bit. The positive transition filter is set by the
:STATus:QUEStionable:PTRansition command.
If a bit in the negative transition filter is set to 1, then a 1 to 0 transition in the
corresponding bit of the CONDITION register causes a 1 to be written in the
corresponding EVENT register bit. The negative transition filter is set by the
:STATus:QUEStionable:NTRansition command.
See "STATus Subsystem" in Chapter 5 for details about these commands.
