Programmers guide

6.2.5

This register controls the diagnostic current enable and polarity.

This register can be read or written to. All new data programmed into this register will be

acted upon the rising edge of CSN even during a timed actuation.

ODCHx / ODCLx – HBDCHx/HBDCLx

These bits set the output diagnostic current. When the corresponding bit is set there is a

current imposed (IDIAG) on the integrated drivers (ODCH/Lx) or external drivers

(HBDCH/Lx). A sink and a source current cannot be enabled simultaneously.

It is not recommended to use the diagnostic currents when the outputs are being used. That

is during timed actuation or during output override.
