:STATus Subsystem
• The value of unused bits is zero when queried and is ignored when set.
• A TRUE bit in the positive transition filter specifies that a positive
(FALSE to TRUE) transition of the corresponding bit in the Operation
Condition Status Register generates the corresponding event in the
Operation Event Status Register.
• At power-on and STAT:PRES, the positive transition filter is preset
such that each bit is a 1 (TRUE).
• This value is unaffected by *RST, *CLS, and *SAV/*RCL.
