I have some question.

1. If GPIO_0 is registered by GPIO_MUX_CTRL, what is the polarity of LED_3 ? Is it Active Low or Active High?

2. Also, can we select active high or active low by the register?

Hi Koji,

1. If GPIO_0 is configured as LED_3, the pin is Active High by default.

2. GPIO polarity can be either Active High or Active Low. Register 0x19, bit 14 controls the GPIO polarity.
