CONDition register.
The CONDition register is directly written to by the hardware
or the summary bit of the next lower register. Its contents reflects the current
device status. This register can only be read, but neither written nor cleared.
Reading the register does not change its contents.
PTRansition register.
The Positive TRansition register acts as a transition filter.
Upon transition of a bit of the CONDition register from 0 to 1, the associated
PTR bit decides whether the EVENt bit will be set to 1.
PTR bit = 1: the EVENt bit is set.
PTR bit = 0: the EVENt bit is not set.
This register can be written and read. Reading the register does not change its
contents.
NTRansition register.
The Negative TRansition register also acts as a transition
filter. Upon transition of a bit of the CONDition register 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 register can be written and read. Reading the register does not change its
contents.
With the aid of these two transition filter registers the user can define the status
change of the CONDition register (none, 0 to 1, 1 to 0 or both) that is to be
reported in the EVENt register.
EVENt register.
The EVENt register reports whether an event has occurred since
its last reading; it is the “memory” of the CONDition register. It only registers
events that have been reported by the transition filters. The EVENt register is
continuously updated by the instrument. It can only be read by the user. Reading
this register clears its contents. This register is frequently referred to as the
overall register.
