Configuration register C (address 0x02)

7.4.1

DDX® power output mode

The DDX® power output mode selects how the DDX® output timing is configured. Different

power devices can use different output modes. The recommended use is OM = 10. When

OM=11 the CSZ bits determine the size of the DDX® compensating pulse.

7.4.2

DDX® variable compensating pulse size

The DDX® variable compensating pulse size is intended to adapt to different power stage

ICs. Contact ST for support when using this function.
