Value after reset: 000000xx
For general information please refer also to
DCH_INH ... D-Channel Inhibit (NT, LT-S, Int. NT mode only)
Setting this bit to ’1’ has the effect that the S-transceiver blocks the access to the
D-channel on S by inverting the E-bits.
The pin DCI, which performs the same funtion, is internally combined (EXOR-logic) with
DCH_INH, i.e. either setting the bit to ’1’ or pulling the pin high will block the D-channel
access, however activating pin and bit simultaneously must not be done.
If this bit was not set before, reading DCH_INH reflects the status on pin DCI, i.e. the
D-channel inhibit function is controlled by the pin. If the function should be controlled by
programming DCH_INH, the pin DCI must be strapped to “0” or “1”.
