6.5.2 Input CPU Connection
For a correct input read sequence, the common stimuli pins for all inputs LDINA#
and LDINB# as well as the pins HDIN0# to HDIN3# for the corresponding inputs 0
to 3 must be actively set to a high level. A settling time of at least 100us must have
elapsed, before a valid read can be performed.

6.5.3 Input Test Feature
Each input can be fully tested during normal operation. The test will not be
disturbed by any input state or state change within the given nominal input limits.
The test will overwrite the current input information, so the user must take care
about the system functionality during the test sequence.
A valid input state can only be read if all input test stimuli are disabled for this input.
