iMX28 : PWM output pin behavior

[koichisakagami]

Dear community,

We design the custom board .
We need information about PWM output pin behavior.

After the PWM register setting is completed,
we disable a PWM channel_xx by the PWM Control and Status Register (:PWMxx_ENABLE => 0).

Question1.
Then, What is the PWM output state ?
Is it high impedance ?

Question2.
    Then, Can the internal keeper be enabled / disabled separately ?

Best Regards,
Koichi Sakagami

Hi koichi

1. yes it is high impedance

2. this can be done for some pads (not all), check

HW_PINCTRL_PULLx register descriptions.

Best regards

igor
