CONDition
register
The CONDition register is directly written by the hardware or the summary bit of
the next lower register. Its content reflects the current device status.
This register can only be read; it cannot be written to or cleared. Reading the
register does not change its contents.
PTRansition
register
The Positive TRansition register acts as a transition filter. When a bit of the
CONDition register changes from 0 to 1, the associated PTR bit determines
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 to 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 determines
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 to 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
recorded 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 device.
It can only be read by the user. Reading this register clears its contents.
This register is frequently referred to as the overall register.
