DBN_x

The DBN_X bits disable the braking mode on specific outputs. When this bit is set the

dynamic braking function does not work for that output. This allows the selected output to be

used for other functions besides door lock.

6.2.2

This register sets up the groups for paralleling outputs as well as a few other functions. This

information remains in the register even after actuation.

This register can be read or written. While new data can be written to the register it will not

become effective while in timed actuation or while in indefinite braking mode. The new data

will become effective:



If the data is changed during a timed actuation, then the new data value will become

effective at the end of the timed actuation (ton + toff).



If the data is changed during indefinite braking or during a timed actuation with

programmed indefinite braking, then the new data value will be taken into account only

after a write operation on to register 01H occurs or unless a new timed actuation is

triggered by EN_OUT rising edge.



If the data is changed outside of a timed actuation and outside of indefinite braking,

then the new data value will become effective upon at the rising edge of CSN.
