part can only be read, but not written into or cleared. Its contents are not affected
by reading.
PTRansition / NTRansition status register part
The two transition register parts define which state transition of the
CONDition
part (none, 0 to 1, 1 to 0 or both) is stored in the
EVENt
part.
The
Positive TRansition
part acts as a transition filter. When a bit of the
CONDition
part is changed from 0 to 1, the associated
PTR
bit decides whether
the
EVENt
bit is set to 1.
●
PTR
bit =1: the
EVENt
bit is set.
●
PTR
bit =0: the
EVENt
bit is not set.
This part can be written into and read as required. Its contents are not affected by
reading.
The
Negative TRansition
part also acts as a transition filter. When a bit of the
CONDition
part is changed from 1 to 0, the associated
NTR
bit decides whether
the
EVENt
bit is set to 1.
●
NTR
bit =1: the
EVENt
bit is set.
●
NTR
bit =0: the
EVENt
bit is not set.
This part can be written into and read as required. Its contents are not affected by
reading.
EVENt status register part
The
EVENt
part indicates whether an event has occurred since the last reading, it
is the "memory" of the condition part. It only indicates events passed on by the
transition filters. It is permanently updated by the instrument.
This part can only be read by the user. Reading the register clears it. This part is
often equated with the entire register.
ENABle status register part
The
ENABle
part determines whether the associated
EVENt
bit contributes to the
sum bit (see below). Each bit of the
EVENt
part is "ANDed" with the associated
ENABle
bit (symbol '&'). The results of all logical operations of this part are
passed on to the sum bit via an "OR" function (symbol '+').
ENABle
bit = 0: the associated
EVENt
bit does not contribute to the sum bit.
