HSx.1 HSx.0 Description Remark
0 0 default OUTx High impedance
If a driver is enabled by the control register AND the
corresponding PWM enable bit is set in CONTROL_3
register, the output is only activated if the
corresponding PWM input signal (PWM pin or internal
PWM signal) is high.

disabled (high impedance)
The ECFB−pull−down transistor can only be activated
if the DAC output voltage is set to 0 V (DAC[5:0]=0). If
the PWM enable bit CONTROL_2.ECFB_PWM1 is
set, the output will only be activated when the PWM1
signal input is high.

By enabling the electrochromic mirror controller
(ECEN=1), the output driver for the external pass
transistor (ECON) is enabled. In addition, OUT6 is
activated, regardless of the setting of
CONTROL_1.HS6.
