The electrochrome control is activated by setting this bit to ‘1’.
This enables the driver at pin ECDR and switches OUT10
directly on ignoring bit OUT10_HS on/off.
0
ECFD_LS on/off
Read/write
0
The corresponding output driver is activated, if this bit is set.
Setting the PWM enable bit, the driver is only switched on, if
the PWM timer enables it.
